alt Hacker NewsI built one of these. It is not possible to do so for 60$ anymore since the board itself goes for 150+. On top of that you still need a PSU, NVMe, a high pressure fan, DP to HDMI adapter, possibly BT and Wifi adapters, and a 3d-printed or DIY case.
It is also a very hacky build. You need to flash the BIOS which enables a few interesting unlocks: from 24 to 40 GPU compute units and 6 to 8 CPU cores. It's a bit of a silicon lottery and will depend on your specific board and you need to test everything thoroughly yourself, honing on a config that works for you.
The software side of things is Linux, so if you're familiar with setting it up it shouldn't be difficult to go through the different steps. There are a few distros that work well. I use Bazzite and boot directly to Steam big picture, the UX is great. You can exit to desktop and you have a fully usable Linux box that you can play around with from the comfort of your sofa.
One of the downsides is that it uses a lot of power when idling, about 80W. I just turn it off after using it. I'm working on a QOL feature: an ESP32-based power switch that starts the board when a specific BT device is detected (usually a controller). Once everything is setup the board works very nicely. It can be a bit loud depending on your fan/case combination. I'm currently printing this one[0]
It delivers about the same punch as a standard PS5. The hardware is remarkably similar, and much better than mini PCs set up with AMD APUs, unless you go Strix halo but that is another price league (10x). You can play Cyberpunk 2077 decently on it on settings similar to an AMD RX 6700XT or slightly below RTX 3070.
A pretty impressive number is the memory bandwidth at ~410 GB/s, which should run local LLMs like Gemma 4 or Qwen3.8 27B at decent speed but with limited context size as its just 16Gb
Would I build it again? It was a lot of fun, but financially is not a crazy deal if you need to buy all the materials and factor your time in. Still much cheaper than a Steam Box!

what for? just use DP
Was it possible to build it for $60 when you built it though?
As for the idle dray, a lot of PC's have Wake On Lan so you can power it on via a special IP packet. I could't get it to work on mine, so i pus an esp32 based power monitoring plug in front of it, and configured the PC to power on directly when powered. When the power monitoring sees the PC sleeping for some time, it cuts the power. I control the plug via home assistant, so i can switch it on remotely
