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.
