Good article. He choose a fractal design case which I really like (the company not the specific model).

I had all kinds of thermal problems with a too small case that I used for my truenas build. It would turn off without any trace in server logs (I have real server HW and therefore expected something in logs since there is a whole separate computer for this).

I changed the case from a NAS case to another fractal desfrign case with lots of space for drives and heatsink. All thermal issues disappeared.

I just wanted to warn anyone who is building to take this seriously. Some HW drives generate a lot of heat.
