Small and powerful gaming PC

I had a dream, a beautiful dream in which I built a small and powerful gaming computer. The current one I have is also not too big. I also built it myself and it still has the possibility of expansion. But I think it could be better, smaller, faster. So I started to looking for some parts in on-line stores and wholesalers. I spent few hours and I think I am happy about the results.


My plan is to build a small (not necessarily the smallest) desktop computer with high computing power. Allowing to play popular games with high graphic settings, which will also enable the use of this equipment to experiment with cracking hashes and passwords.

As the final amount is quite large, I will be buying components from month to month or less. Hence the plan is to collect all components in the coming year and at the end of the year reassemble the whole and test it.

Due to the time it can take to buy everything (unless I win the lottery) some components may change. I will try to keep this article up to date in order to keep you informed about changes and progress.


The plan is to buy only new parts, but the alternative (where possible) I also give approximate amounts of used parts.

Below I present the components,specs and their approximate prices.

Possible problems

With such a small case and components of this type, the space, temperature and noise will be a problem.


The sizes given in the specification for all elements indicate that everything should fit. The processor cooling heatsink will not interfere with the memory. A possible obstacle may be hard wires of the power supply, which if they do not work well, they will have to be replaced with more flexible ones.


All elements have their fans, which should cool the whole without any problems even during the most demanding tasks. Case allows the installation of additional chassis fan, top fans (80mm fan x2 or 92mm fan x2) and bottom: 80mm fan x1. CPU cooling system is sufficient for i7 processor. If we would like to upgrade CPU to i9 then some power restrictions should be adjusted in the BIOS (suggested maximum power limit: 130W) or replace the cooling. Unfortunately, I could not find the CPU cooling with a maximum height of 60 mm, which would support the i9 processor.

Anyway it can be hot inside.


Fans, fans, fans! Too many fans. Probably fans from GPU and CPU are not so noisy but if I will add optional chassis fans maybe starting to be loud. Depending on the temperature inside, a decision will be made whether to install chassis fan or not.


It’s a bit much for my budget, especially since I’m not a big player. Nevertheless, I will try. I hope that in a year it will work, and if not a year, it will take a little longer :) if you would like to support the construction of this computer, you can contribute by sending a few bitcoins -> 1CR4ZqYSvsjc45ShBuXTU1qrKXgrBRkxFp. Thanks!

If you have any comments or tips about the configuration please share with me in the comments. Maybe I omitted something or made a mistake somewhere. I will be grateful for hints and thoughts.


Small updates about changes in project and what I already have.
