I've been running my homebuilt ABIT BP6 with dual matched Celeron 366 MHz overclocked to 550MHz for about three years now. Runs 24/7 and is pretty stable except it occasionally burps when it overheats (even though it has about 8 fans ;)
The ABIT board is a true work of art...(runs Linux RedHat configured for symetric multiprocessing, of course: is faster than our $25000 SUN which we bought just five years ago)
Never heard of 'em. Time to do a little search. ;-)
