The huge storage space coming, of course, from IDE. Of course you
could have sacked the mucho-expensive SCSI-2 card and horrendously
expensive SCSI-2 hard-disk and got three IDE hard disks of double the
size for the same price, but then that would be too sensible.
SCSI has it's place and is good where you _need_ to have it (mainly
for low CPU occupancy, HD intensive apps or where adding daisy-chained
devices is beneficial, but for loading GPL it's daft.
He also wastes a truckload of money when he can buy a couple of huge
IDE drives from the start.
