Buy a mobo with 4 IDE chanels.  CD-Rom on one, burner on one, two hard drives
then add a pair of 3ware cards (4 chanels each, accelerated, with linux
support).  That will allow you 10 hard drives.  Assuming two boot drives, 
that gives you 2 raid 5s to stripe.  So easily a terabyte, but with raid, 
probably only 640 megs of bullet proof storage.

Under certain circumstances, the stupidity of IDE becomes a question not of
will it degrade your performance, but rather are you going to put up with
it?  For instance, point to point FastE is, to my understanding, just as fast
as FDDI, but you still just know it is inferior.  Under some circumstances,
IDE is just as fast and data safe as scsi, but still, you just know it is 
inferior.
