It's certainly not bad already.  There are consumer cases that will take 15
to 18 hard drives internally.  There are motherboards with 6 or 8 SATA
ports.  And there are simple SATA cards that are cheap enough these days.  I
think I got a 4 port for $40 for my machine.  I see "buy it now"'s for 8
port cards around $100 on eBay.

16 ports * 1T drives is ~15TB.  Make it 1.5T drives and RAID-Z2 and you have
more protection and a bit more space.
