Adaptec have 64-bit versions of their quad-port fast cards. I think they have 66MHz versions as well. At any rate, you might want to consider the Tyan Thunder 2500 as a platform for this sort of work. You'll want to think about memory bandwidth (which this board has in spades) as well. -- ... every activity meets with opposition, everyone who acts has his rivals and unfortunately opponents also.
