Brian, If you are just using this as a workstation the SCSI disks may be a bit of overkill. Don't get me wrong large reads will be fast but for the most part you will be working in a shell, vi/emacs, browsing the web, etc.. none of these operations are disk intensive. If you are interested in data integrity you could save your self a few hundred bucks and get 2 120GB IDE disks put them on different channels and use Linux to do a software mirror. RH9 will allow you to set this up at install time. If you are interested in general speed improvement I would look at bus and cpu clocks with a focus on the ram bus. It sounds like you have money to spend, you may also want to look at an SATA Intel 865 board. This board offers dual channel DDR RAM slots, SATA and regular ATA, go with the 3GHz HT cpu. Looks like any way you go you will have a screamer! Matt
