I had an old Abit BP6 (if you look, I think that my first AT post was about it) with dual 333@550 celerons. That was pretty old school. Think I threw that board out earlier this year...up to that point I HAD been using it quiet a bit....
also have this box as an old file server...Compaq Proliant

Yep, that is 8 P3 550's....it's a tank of a machine, but I have a hard time getting rid of it, because the damn thing will run forever. We had 400+ days of uptime at one point. only 53 right now though (need to hook the UPS up to it again)
