Fitting a server with desktop hardware in a 1U rack mount chassis (fedia.io)

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?

Edit: I ended up giving up on 1U. Instead I bought a miniITX motherboard and am going with this 2U dual miniITX chassis. Way more vertical space to work with and it gives me the option to add a second server (something I want to do once memory/storage prices calm down) within the same rack space.

Do you think a passive heatsink like this would work? As I understand it 1U servers usually use a passive heatsink with fans pushing air through the case horizontally, rather than an active heatsink with a fan. Noise isn't a problem since it's in a server room so I can cram in as many fans as is necessary.

Yeah that should work. Servers usually live in a cooled server room and run their fans full speed. If you can do that, you'll be fine.
