the best option for dual PIII's under 850 would have to be (in my opinion) the Tyan tiger 100. these are hard to find since they're discontinued. but, man, they ROCK! use the 440bx chip (superb stability) and supprt for coppermine to 850 mhz. other than that, for a basic home-use server the Tyan tiger 133 is also excellent. it runs on the Apollo chipset from Via. I runa couple of systems witht his chipset, and its older brothers, and have to admit that it performs very well but is a high maintenance wench! constant tweaking and bugs. Once you get the VIa chips all configured right, they do kick ass, but what you want in a server is quiet, never hick-up, stability. track down a tiger 100 and be a proud man.......
ignore everything i say
