Serverworks chip sets

We've had good luck with the Supermicro 370DLE. Using high quality CAS 2
memory we saw significant speedup in our quantum chemistry codes. I'm also
interested in the HE version but I don't think I can talk the guys here into
spending the money to check it out.

We've also had good luck with ATA/100 ide hard drives (ibm) on the Promise
controller. We've gotten 50MB/sec reads and writes with "real" code. I like
SCSI but it's hard to justify the expense when you consider that you can get
a 64GB ide drive and an ATA/100 controller for under $350. My experience is
that good SCSI drives fail just as often as good quality  ide drives. Biggest
drawback is -- for performance you should only use one drive per controller.

Hope this helps
