Tyan Trinity 400 (1854).
It also has the advantage of also having a Socket 370, so you can upgrade to a 370 cheap and keep the same MOBO.
It's pretty stable, mine was running for a year and a half, no hitches, no glitches, no BSODs...no complaints from me, I liked it. The only reason it's not on-line now is that I got bit by the Dual bug and I snatched the proc from it to build a dual system.
FWIW
