Reminds me of my early-1990s home network server: a late-1980s IBM PS/2 Model 80, a 386 tower built with a moulded iron case. Super tough, fancy 32-bit IBM expansion bus. 4MB of RAM on the motherboard, another 4MB in an expansion slot.

I attached a couple of big SCSI drives and ran Windows NT 3.51 Server on it. When not logged in, it only used a couple of megs of RAM for the OS so file serving performance was tolerable -- and the hardware was literally bulletproof. I dropped one down a flight of stairs in my first job. The computer survived but it knocked lumps out of the concrete stairs on the way down.
