A few weeks ago, I decided to build a custom wall mount for my PC! I’ve been wanting to ditch my old Dell computer case and also make the heat sinks easier to clean. The key components are a PCIe extender for the GPU with at least 30 cm cable length, and a low-profile CPU cooler like the MasterAir G100M. The build is designed to rest on two angled blocks mounted on studs 16″ apart.
Update 2021-07-31: This is working great! The PC runs quiet due to excellent air flow, doesn’t take up floor space, and stays clean due to its elevated position.
