I had a couple SGI 1100 several years back although being rather plan and nothing fancy with them they were really insanely stable boards. When I first ran the Windows Whistler Beta on it I had an uptime of over 200 days. I also never had any issues running most popular flavors of linux. There is no uncommon or less common hardware on them and if I remember right the motherboards were actually OEMed from Intel and used ServerWorks chipsets. I even used the motherboard out of one in my workstation from 2000 to 2004. The only real issue I had with them is that almost all sound cards would prevent the system from POSTing and I was forced to use a USB sound card if I wanted sound.
