I have found a old pc (pic related from when he was used) and

It's worth it if you have the room for it. I have a windows 98 machine my spare room, and it's a lot of fun. I wouldn't build a retro PC though, I would go to a computer recycling place and just pick something up.

Also you can still get a lot of computer stuff from that era for basically free nowadays, which is nice.

It looks like a standard 4U 19" rack-mountable server case.
Probably ATX so you could fit most mainboards made between 1996 and today.

Yeah that's just a rackmount case, nothing really special. You can of course put old 90's guts in there. The fan might be loud though. I once used a Pentium II era server as my desktop for a couple months, and the noise was insane. Well it probably didn't help that it had SCSI-2 UW disks (spinning at like 15k rpm?), but I think even just the fan was pretty damn loud compared to normal desktop machine.

Anyway pic is more typical of old desktop machine. I think this one's a Wang 286 clone, but the 90's desktop cases didn't look all that much different, except having 3.5-inch floppy drive and CDROM instead of those 5.25-inch floppy drives. Early 90's cases often had both type of floppy drives, since that was the transitional period.
I think that button above the LEDs in the middle might be turbo button. Even my 486DX/33 case had one of those, and I've seen quite a few Pentium systems with one as well.
