Since I after two years finally put together my new server I directly stated to think about an alternative way. The one that has occupied my mind most recently is to build a couple of smaller computers specialised for their purpose. Thee are a couple of really nice small NAS cases like the Jonsbo N3 and the Silvestone DS380 which both are less than 30x30x40.
Now I’m trying to find similar cases that can hold an atx or matx card, one or two decent sized graphics cards, and lots of fans. With a 10G+ network card in this and the NAS most of the disks can be stored in the NAS and these cases will only need space for two 2.5" drives or something similar.
Jonsbo has a couple of cases suitable for this, D41 Mesh and D31 Mesh were the first ones to catch my eye. Both can fit 2x140mm in top and bottom, 1x120mm in front and back. I’m an old man who still haven’t gotten used to computers not being greybeige any longer so I’d prefer if they didn’t have windows, but hey, I guess you can’t have everything.
