That's why you want a small local shop. They have a direct interest in helping you - large suppliers usually don't care about people with one or two boxen. Also in my experience building yourself gives much better results.

Also SCSI is expensive - for the price of two scsi disks and a controller I can get a 6-disk software RAID5 that will most likely outperform it and has about 10x the space. For most uses el cheapo SATA will be better (but SCSI / SAS / FibreChannel has its place) > Ram more than processor is fundamental so try to keep always > a slot free for future upgrades and don't buy ram from vendor but buy it > yourself : it's cheap! ... and get as much as you can.

Split the disks - 2 for mail, 4 for fileserving or whatever. That way there won't be much crosstalk between the applications (think fileserving making mail crawl) One more reason to get many cheap SATA disks ... That's, obviously, just my opinion :-) but it has served me well. Patrick -- Stand still, and let the rest of the universe move
