Need help choosing MB/RAID card

[Warren Melnick]

A friend asked me to put together a system for him to do a bunch of hosting on.  Based on his needs, I want to set up a machine with dual CPUs (P3 most likely) and RAID 0+1 for the databases.  The questions are these:   Which motherboard does SMP (very) well with P3 (or P3-type, can be AMD) processors? Which card will do RAID 0+1 and be fast and compatible with Linux (RedHat most likely)?   Thanks, Warren
