Let’s not pretend there haven’t been some crazy computers built over the years, but this toaster game PC build (yes, you read that right) may be one of the most incredible. I found this unusual mini gaming PC on Reddit, and it immediately caught my attention. Not only is the DIY case, well, toaster-y, but it also has some incredibly powerful specs hidden inside.

On paper, “The Toaster” (as this unique PC build is called) can easily compete with some of them best gaming computers you can buy. It combines the best of Intel and Nvidia has to offer, mix one up Intel Core i9 14900K – the chip maker’s latest generation flagship – while packing a full size Nvidia GeForce RTX 4090 Inside.

A quick point before you worry about the heat: this computer unfortunately can’t make toast, but on the plus side, it doesn’t get too toasty either. Combining an RTX 4090 GPU and i9 14900K gaming CPU together inside a 13-liter case could be a recipe for disaster, but thankfully Billet Labs (the UK-based DIY builders behind this PC) have integrated an ingenious water-cooling solution. It uses custom loops and pipes and a specially made water block, to keep both the CPU and GPU cool.

This water-cooled design has given this mini gaming PC a huge thermal advantage. During Billet Labs’ tests, processor temperatures under load stayed at around 161°F (72°C), with only minor fluctuations. However, the water-cooled RTX 4090 stayed at an incredibly low 132°F (56°C) under load, with the hot spot only reaching 158°F (70°C). Those CPU temps are amazing, but the GPU temps are closer to a miracle.

Everything about this computer is simply a joy to look at, although it was probably less fun to build, given how compact and complex it is. Billet Labs has documented the entire build process, and when you see it come together, you’ll really appreciate the painstaking effort the builders put into bringing this computer to life. The build quality is just incredible, and with the final product on its way to a Billet Labs customer thanks to this (very expensive) custom PC sale, we’re sure they’ll be very happy with the end result – I know I would . be.

According to the original Reddit postit took around 150 hours to build (not including filming time) and cost around $6,300 / £5,000. You can watch the entire build process, from start to finish, across several videos at Billet Labs YouTube Channel to see how it all came together. Spoiler: it wasn’t easy!
