how to build your own cheap gaming pc on a budget lenovo m83

It’s about bloody time to build myself a new gaming PC…On a budget!

Want to know a secret?

How to build your own cheap gaming PC on a budget and on basis of a desktop office PC Lenovo 83
Here it is my new future cheap gaming PC on a budget – a desktop office PC Lenovo ThinkCentre M83

In the last few years, with all my friends playing only on XBOX, I used my PC for office stuff.

Yes. Tedious, mundane, office work.

But.

I felt a hunger to go back to real gaming, or what we like to call here at PCPH as “classy gaming.”

I needed to build a new Gaming rig – and fast!

Back to Basics: How can I build a gaming PC on a tight budget?

What. A. Pickle.

The words “performance” and “budget” aren’t usually used in the same sentence.

This awkward situation puts me in the same boat many of our readers find themselves in! If you’re like me, you may be asking yourself this same question:

“How on Earth can I build a gaming PC on a very tight budget?”

Yes, I’m aware that there are many excellent tutorials on YouTube and a lot of written material as well.

But building a budget rig is all about the money, making it tough to reproduce the exact same PC build. After all, we’ll only be looking for used parts on eBay, and PC parts on a video may not be the exact same thing you get online.

The gaming desktop tutorial I follow on Youtube

Youtuber “Hardwaredealz” shows us how to build a cheap gaming PC based on an older office desktop PC (you can get the subtitles in your own language, just click in the bottom right corner on CC, and then on the setting’s symbol next to it, click on “Subtitles/CC” – Autotranslate – and choose your language)

To make matters worse, I haven’t kept abreast of new developments made in the PC industry these past few years. My information on GPUs, CPUs, mainboards, and how these babies play together is a little dated.  

Let’s find out if our version of their PC will work.

Soooo.

Here I am, wanting to finally play my favorite (often older) games on a PC.  But then it dawned on me that all I have right now is a single core Celeron Mini PC! Before you jump to any conclusions, I’m not throwing shade at my own office workhorse!

It’s amazing what my Celeron Mini-PC can do for its affordable price and low-level hardware. It’s enough for doing office stuff, but Steam won’t even fire up!

Ghost Recon I on Windows 10 with Steam?

Based on some comments, it seems that I can play the old Ghost Recon [XP only] on today’s Window’s 10 Desktop via Steam. There’s no way in hell I can do that with my Xbox, and  I can’t wait to try it!

This tidbit of info got me wondering how I could build my own cheap gaming PC, so I did a little research.

I spent many hours scouring the internet for answers when I finally came across a video that inspired me. It’s the video I mentioned above, from German YouTuber Hardwaredealz.

Hardwaredealz had a nifty little idea.

Their suggestion: buy a high-quality, cheap, and branded office PC system that’s used. That’s right. It makes sense, actually. Think of it as a high-quality PC bundle that you can build around. This Youtuber has a few recommendations for this project PC build:

  • Lenovo ThinkCentre Desktop PC
  • Dell OptiPlex Desktop PC
  • Basic specs are quad-core Intel CPUs with 8 GB of RAM

For this video, he got a used Lenovo ThinkCentre on eBay with 8 GB of RAM and an Intel i5 2400 quad-core for only 85 EUR. Then he installed an SSD drive and a used GeForce GTX 950 graphics card that he bought for pennies on the dollar. Oh, and he also overclocked the GTX after installing it.

Sounds simple enough…until it isn’t.

Using a pre-built PC as the core of your Gaming System needs Extreme Patience!

To begin with, there’s one caveat with this sort of gaming PC build:

  • You need to have a TON of patience!

Why?

Because not all the parts you need will be available on eBay and eBay Classifieds when you look for them. Building your gaming rig from old parts takes some effort and a considerable chunk of your free time.

The video’s creator also warns that parts can be more expensive on eBay than on hardware forums and marketplaces, like eBay classifieds. So make sure you look around and exhaust all other avenues when searching for PC parts, not only on eBay.

Their Footsteps to build a cheap gaming PC

I decided to follow the video author’s suggestions.

I searched for used computers and parts on eBay and eBay Classifieds. It was tedious work! There was a lot of discussions, negotiations, and questions with various sellers. After the dust settled, I finally ordered a 5-year-old Lenovo ThinkCentre M 83.

The old office rig had a quad-core i5 Intel 4430 CPU @ 3 GHz, 500 GB hard drive, 4 GB of RAM and Windows 10 pre-installed.  Ot also came with an old GT430 graphics card.

Date: March 23rd

So far, all I did was move my 120 GB SSD Windows 10 boot drive from my old Zotac Celeron PC to the Lenovo M83. The whole point of this exercise was to:

  • Speed up the system
  • Not having to reinstall everything

Windows 10 took the move to its new home without any problems. It took about 20-minutes for the OS to detect the GeForce GT430 and download the correct drivers for it. I have to admit that I was unsure if Windows recognized the card or not. But, my fears abated when everything went according to plan.

Kudos to Microsoft for doing a masterful job at improving Windows 10!

Now, let’s go back to the GeForce GT430 video card…

Cost for my future gaming rig so far: EUR 109 incl. delivery costs.

No added value: GeForce GT430

The GeForce 430 is an ancient graphics card, with one gigabyte of VRAM. It’s also one of the slowest cards you can have on your system based on available speed tests.

I tested the GT430 to see if I absolutely needed a new graphics card, or as the video suggests, to invest in a new GPU.

only 12 frames with fraps on Counter Strike Go with gt430 on cheap gaming pc
only 12 frames with FRAPS on Counter Strike Go with GT 430

The good news is that I was able to run Steam and play Counter Strike: GO using the rig “as is.” But as you guessed, the frame rate sucked at only 12 FPS (measured with FRAPS)! I was lucky to even get 20 frames per second on this setup.

But 20 frames is still miles away from the 60-80 FPS needed to have an excellent gaming experience.

To be fair to the GT430, I was also getting only 12-20 frames per second because I set the game’s graphics settings to “high.” But for some reason, even if I lowered the game settings to medium or low, the frame rate didn’t go up. I find this super weird…

Experiments in overclocking

I also tried to overclock the GeForce 430. For that, I downloaded MSI’s Afterburner, a helpful tool that makes overclocking a GPU very easy.

Caveat: The only reason I dared to overclock this GPU was that I didn’t care much about it and meant to replace it with a more powerful card.

Interesting note:

In Cinebench and other testing tools, even the highest available MHz settings for the card didn’t improve the frame rate at all!

Cinebench contradicts my personal experience.

For me, CS: GO ran faster having pushed the settings as far to the right as possible. But FRAPS still showed 12-20 fps (frames per second), which is not ideal.

Overclocking the GT430 did nothing

I hope I can discuss this strange behavior with an overclocking expert later, but I am afraid there isn’t any hope for the GeForce 430 card. As it stands, I can’t play any game that requires more powerful specs with the desktop I have right now.

Counter Strike: GO on 12 fps?

All I can say about CS: GO on 20 frames per second is that it kinda works, but isn’t worth your time. It ruined the game for me, and it wasn’t quite what I had in mind.

4GB of RAM is NOT Enough for Gaming

The desktop PC is also slowed down by 4 GB of RAM. Firefox alone can make the Lenovo unresponsive for a time. With the i5 CPU idling at 25% max, and memory consumption at 90%, it takes a lot of disk operations to free up RAM.

Status Update: On Track to hit My budget, but no Gaming PC yet.

As the video suggested, we’ll need more steps and parts to build our budget gaming PC.

  • First, I have to upgrade my RAM to at least 8 GB to cut unnecessary, time-consuming disk operations and speed up the PC.
  • Second, I need to get the suggested GTX950, because the included GT430 GPU is worthless.

Why the GTX950?

I want to make sure that I can replicate the gaming PC as close to the source material as I can (YouTube video). I’ll run into fewer problems and may even avoid them altogether if I follow the suggestions.

As far as graphics cards go, the GTX950 is not as power-consuming when compared to other GPUs. Upgrading to a more power-consuming video card could mean I might have to replace the weak 280 W power supply the Lenovo M83 I bought came with.


And it seems many people are on the lookout for a GPU that doesn’t need an extra power supply. So anyone upgrading an old office PC is on the hunt for such a card, i.e., the GeForce GTX1050 ti.

As a consequence, these cards are much more expensive, even or especially on the second hand market.

Searching for used RAM

As described, the performance of the 4 GB RAM is pretty bad. On eBay Classifieds, I searched for RAM with the specs that I needed for this Lenovo. I googled and downloaded the ThinkCentre M83 specs PDF:

Memory 32 GB max, UDIMM, PC3-12800 1600MHz DDR3, four 240-pin DIMM sockets
*System automatically clocks down for processors with 1333MHz memory controller

After some research I found two 4 GB (12800 1600MHz DDR3) RAM modules on eBay Classifieds. Awaiting postal delivery.

Cost: 33 EUR incl. packaging & delivery.

GeForce GTX 950

The YouTube video by Hardwaredealz suggests buying a cheap GeForce GTX 950 – and in their video the card fits perfectly into the Lenovo tower.

So, I started searching for this card on eBay Classifieds and lo and behold – I immediately found one in my area! We agreed on a price of EUR 50 for this used card (no delivery costs).

The total amount I spent so far is below 200 EUR.

and here it is ... the Asus Strix GTX 950 graphics card with 2GB - should I have bought a low profile card instead?
and here it is … the Asus Strix GTX 950 graphics card with 2GB – should I have bought a low profile card instead?

Total cost so far: 109 EUR + 33 EUR + 50 EUR = 192 EUR.

Costs below 200 EUR. And according to the video, I should own (in parts) a pretty OK budget desktop gaming pc now.

Status 24th Mar: All parts bought

The desktop PC is here and up and running.

The 8 GB RAM modules are on their way.

The GTX950 is here.

But now the problems start to creep up on me and challenge my level of technical expertise.

Hit a Roadblock: the GTX 950 & M83 give me major problems

Though I bought (visually – they never said what exact Lenovo build they used) the exact system they used in the video, reality bit me pretty damn hard.

  1. The GTX950 doesn’t fit on the M83 motherboard (too long=
  2. I have no way of powering the GTX950

Here’s an inside view of my Lenovo with the old, short GT430 GPU still in. She fits the space perfectly and doesn’t need any extra power.

my motherboard seems to be different from the Lenovo Manuel bought

See the two red squares?

The bigger one is a massive connector of some sort, about 3-4 cm high. It sits in the exact same space the cooling fans of the GTX 950 would take. There’s no way of inserting the GTX 950.

Shoot.

Roadblock #1: Not enough space for the Strix GTX 950

I wasn’t able to plug the GTX 950 at all. There’s no available space.

The YouTube video doesn’t show or mention anything about getting a shorter video card.

So, I bought a “normal” length GTX950 on eBay Classifieds.

Also, the Lenovo M83 is a tower (not a Desktop or Small Form Factor -SFF), so I shouldn’t be having any issues.

But I do.

Whoever designed the motherboard doesn’t seem to like modern graphic cards.

Removing the Cooling fans of the GTX 950

Only after I loosened the cooling fans from the card was I able to plug-in the card into the PCI e slot. I used a little force, and it didn’t feel smooth at all.

Would the GTX 950 survive reduced cooling?

Can a modern graphics card survive if the cooling fans are not directly situated above the cooling rib? What if there’s a slight angle and there’s more space between the fans and the rib?

I have three options:

  • Either, I can somehow change the height of that connector, so the card has enough space
  • Or, I can try a card with loosened fans
  • I need another card :(

Solution idea: Angled connector?

Question: Is there an angled connector to reduce the height of that connector? Right now I don’t even know what cable comes out or goes into the motherboard here. So no idea what to search for.

Or…

The card must “accept” the fact that the cooling fans are a little “off ” and blowing in at an angle.

Roadblock #2: No Power for the GTX 950

Take note that the manual lists the M83 as a “tower,” so I shouldn’t have any spacing problems adding PCI cards at all.

But also there is zero unused power connector, not to mention a 6 Pin MOLEX.

empty power molex 6 pin
empty power molex 6 pins

I can only assume that the creator of the video used some extra cabling and connectors to power the GTX 950.

I right now have no idea how how to power the card (if I could insert her).

Lenovo – enough Power?

Speaking of free power connectors: I even had to sacrifice the DVD drive’s power cable for the SSD. It seems Lenovo tried to save as much money as possible on the internal power options!


This is the only free connector at all - What is this cable and can I somehow connect it to GPU with adapter?
This is the only free connector at all – S-ATA – but no power connectors

Status March 24th

So here I am, stuck in a time loop like Bill Murray in Groundhog Day! I’ll be reaching out to the creator of the video to ask for advice.

I’m also still waiting for delivery of the 8 GB of RAM. The PC’s CPU is idle, but the disk is always running to free up RAM space, which often makes the PC unresponsive.

Note to self: I still need to re-power the DVD drive I sacrificed for the SSD drive.

UPDATE March 24th night

The very helpful Lenovo forums have suggested what adapter I need and where to get power for the graphics card. (see #11 in the M83 mainboard manual).

The power connector going into the GTX 950 is a 6-pin MOLEX and it seems I need to connect that to the 4-pin power connectors (#11 on the manual page 73). More research is needed for the connector etc.

Update 10th April

Was pretty busy with other stuff in the last 2 weeks, but now my gaming PC build is finished, but some major work was necessary, something I was very scared to do but had great help and mentors from an unexpected source.

What I did is I kept looking for the short version of the GTX 950 on ebay and eBay classifieds and followed many offers and chatted with many sellers.

Also I sold the ASUS Strix GTX 950 on ebay, and got a little more than I spent, so no damage done here to the project (except more the effort and wasted time – but I learned a lot on the other hand).

Total cost so far: 109 EUR + 33 EUR – 60 EUR = 132 EUR.

And then something great happened … I also started following GTX 960 cards, which are also available in a short version and have much better performance than the GTX 950 (I also started following auctions and offers for the GTX 1050 cards).

One of the sellers on eBay auctions – Amid – turned out to be a great guy and selling computer equipment as an employee, so he knew his stuff.

He offered a GTX 960 cards and we started chatting on eBay classiefied … I told him about my project and what my issue was and showed him the link to this website … and he said “cool, I want to help such a project”.

He showed me that his offfer, the GTX 960, was nearly as powerful if not even more so than a GTX 1050, especially the 4GB VRAM version he offered.

But he said that his card needed extra power (6 PIN Molex too), asked me how much power my Lenovo power supply could handle (270W – I sent him an image) and told me that the card would need way more than that.

So he – simply suggested I exchange my power supply.

UUuggghhhhh….. that’s some place I did not want to go …

But hey, right now I did not make any real progress on my way to nuild my own gaming PC.

So he convinced me that all I needed was some screwdriver, because the Lenovo casing was a so called “ATX” and replacing the power supply was easy as cake.

Well, but I did not have another power supply, didn’t dare to touch that part of a PC – especially with removing and reattaching the mainboard power cabling etc …

But then he made an offer I could not refuse: I buy the card and he will add a 400 W power supply for ATX, which he hadn’t used in years, to support our project (I guess that power supply he could sell for 30-50 EUR).

All I needed was an adapter from Lenovo 14 Pin power for the mainboard to the 24 Pin power cable coming from the new power supply and even sent me the link to get that adapter easily on amazon. The new power supply would even come with the 6Pin MOLEX for the GTX 960.

https://www.amazon.de/gp/product/B00ZRHDQH0/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

I could not refuse this generous offer and so I sent him 86 EUR (incl. packaging) for the graphics card and the power supply.

The adaptor from amazon was 6,50 EUR.

Total cost so far: 109 EUR + 33 EUR +86 EUR = 218 EUR.

Two days later all the equipment had been delivered by DHL and I shikily started to disconnect the Lenovo from power, get me a screwdriver and open the casing.

I then disconnected the cabling coming from the old power supply from the motherboard (2 connectors) and started to loose the 4 screws which connected the power supply to the case.

And then I held the old power supply in my hands…

Quickly I put in the new power supply, connected one cable to the connector on the motherboard — no problems so far.

After that I took the 24 Pin to Lenovo 14 Pin apapter from amazon, and plugged in the biggest plug coming from the power supply … but it did not 100% fit the adapter.

when you build a gaming pc you need expert help

The adapter from amazon came with 24 Pins, but the big connector from the power source only had 20 … I was scared that my information about the amount of Pins that the power supply needed was wrong.

But Amid – he helped me via chat – told me to keep looking, that there was another plug of 4 Pins which belongs to the 20 Pin plug.

And there it was …

problem solved – the power supply comes with 24 Pins -so the adapter fits

It fit perfectly…

Having solved this I plugged the other end (14 Pin) into my Lenovo’s motherboard…

I also removed the old GTX 430 card and plugged in the new GTX 960, using one of the many Molex connectors the power supply supplied in abundance…

Now I reassembled everything, connected the power cable… and very nervously switched on my Lenove…

And..the Lenovo logo appeared on screen. And the system booted perfectly … I did it!!!

And it was much easier than I thought, though without Amids instructions, generosity and remote help the needed evel of expertise would have been way beyond me.

But with some networking (that’s basically what I did on eBay classifieds) I got me a super deal on a game ready grafics card, a new and valuable power supply and expert help in how to assemble everything.

Oh, and I could sell the old GTX 430 for EUR 15.

Total cost: 109 EUR + 33 EUR +86 EUR – 13 EUR = 205 EUR.

And now for EUR 203 my self-built gaming PC, based on a prebuilt office PC, is up and running.

Check back soon course this is a work in progress, I’m curious to see how far I can go with this prebuilt and used office desktop PC, and if I can teach it to become a nice budget gaming PC.
