I have a server with desktop hardware (microATX motherboard and Core Ultra 7 265K CPU) which I use to run a Minecraft server. Its current physical location isn’t ideal, so I’d like to put it in a rack mount chassis and move it to a server room I have access to through my university. However rack space in the room is limited, so it would be best if I can fit it into a 1U space.
From what I’ve heard the biggest issue with 1U is cooling, especially as the 265K can draw up to 250W. It seems like 1U microATX chassis do exist, like this one, but they don’t look like they have good airflow, and I’m not sure where I would get a short enough heatsink. Could I realistically make 1U work, and if so what should I look for in terms of hardware? Or am I going to have to go with 2U?


I’ve been down this rabbit hole and it’s not a good option for standard matx or mini itx. Best I did was get a supermicro board and a supermicro 1u half-depth chassis. It was OK for a while, but the HDDs did not cool off very well.
I’ve now not got a nas just as fast with a radxa rock 2a, a penta sata hat, some FPC cables between them and some cable bodging in a jonsbo n1 case. Drives are happy, less power consumed.
