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.
