This wooden-fronted tiny gaming PC is coming for your game consoles

Size isn't everything as this watercooled small form factor PC build proves that you can fit a whole load of power into something smaller than a PS5 or Xbox.

Not to stoke the fires of a never-ending online battle, but this wooden small form factor PC is an amazing example of how you can make a gaming PC look just as nice, and perform even better, than your standard home console. It uses a Lian Li A4-H20 case, which is smaller than PlayStation 5, yet it houses an RTX 4090 and large water-cooling radiator and pump.

Thanks to our rapidly growing PC building Facebook page, we’ve seen many custom gaming PCs, from mods based on existing case designs to scratch PC builds. You can even submit yours for consideration right here. Here we chat to Etienne about how they assembled and designed this SFF PC build.

PCGamesN: What influenced your build?

Etienne: I have seen loads of SFF builds on YouTube incorporating custom loops and I really wanted to take on that challenge. I have done many custom loops in the past, but never in such a small form factor.

What tools, machinery, and materials did you use, if any?

I used a Dremel to cut the bottom of the case in order to fit the water block. I also used a custom acrylic vented side panel and a front wood panel.

How long did it take you to make this build, from start to finish?

I would say around 30 hours total over the course of a year. This also includes the time of filming the time-lapse while building.

Did you come across any difficulties in designing and making your build?

Yes, the water block didn’t fit at the beginning so I had to cut the case. Also, the reservoir-pump-radiator combo was leaking and it took me hours of troubleshooting to realize that the O-ring inside the pump was displaced.

Are you completely happy with the end result, or is there anything else you’d like to work on next?

I’m happy overall but a bit disappointed by the temperature of the GPU. I’m used to overclocking the hell out of my GPUs because this is one of the goals of water cooling, but with this build, I can’t overclock because the little radiator is too small to extract more heat. Even at stock setting, the load temp is in the upper 60s which is not really different from a good air cooler. However, at least the custom loop allowed me to fit a 4090 in this case.

Would you proudly display this SFF PC in place of a home console in your living room? We know we would, especially given how stunning the final design looks. It would have been easy to fit this all into a much larger tower case, but its size is such a wonderful achievement.
