That gig 'o ram will cost nearly as much as the rest of the system! (ie 
$140 a stick at current pricing for quality RAM)

 From looking at the Abit web page I'll tell you right now the RAID 
ports will be nearly worthless - the HighPoint and Promise "RAID" 
controllers are effectively Windows-only and have very poor performance 
compared to a 3ware ATA RAID card.  They work fine (or rather, the 
Promise cards do) as a JBOD, though.

Everything else should be pretty well supported.

Very much :)

Which bus?  There are 3 or 4 on that board.

The 533MHz bus is ultimately more worthwhile, but the memory bus speed 
is closely tied to the CPU clock speed - in other words, how fast your 
memory goes will depend on which CPU you use.
