I built this over the holidays for myself. If the customer is okay with 
you building something and you can use nfs or smb to mount instead of 
USB, then look at a simple server.

Most mainboards support at least six SATA headers. Put 8 or so GB of RAM 
in it and 6x 3TB drives in software RAID level 6*. This will give you 12 
TB of usable space. I used the Lian-Li PC-A04B chassis, which is a mATX 
case that can support up to 7 3.5" drives, plus has two 5.25" bays. If 
12 TB isn't enough space, add a PCIe SATA adapter and add a couple more 
drives for 18 TB of usable space.

The biggest thing I'd recommend is to get a proper network card. Most 
mainboards come with Realtek NICs and they are utter crap. Personally, I 
like Intel NICs and have a lot of luck with their PCIe Pro 1000/CT 
adapter when budget is a concern.

Note that this won't be fast storage, but it will be inexpensive and 
large. :)

The reason for RAID level 6 is well laid out here;
