3ware will support hardware RAID 5 as of February 15th.  It's a simple
BIOS flash update (to the card, not the system, of course).

Also, it should be noted that Adaptec makes a 4 port IDE RAID
controller:

Promise makes a 6 port IDE RAID controller: http://www.promise.com/

FWIW, I know that one company is delivering a number (at least 6) of
prebuilt 1.7TB (unformatted) linux boxes to Fermilab.  They're using the
8-port 3ware cards with 80GB drives, hot-swap disk trays, dual 850MHz
P-III's, 512MB RAM, a 3Com Acenic gig-e card, dual power supplies
(separate cords), for just under $20K USD.  Not bad, if you ask me. 
Here's the contact details; though, they don't have the server specs
online quite yet:
