Do you have other components going in a rack?
That would be a big consideration as stuffing your systems + home network equipment in a cheap/free rack off craiglist/fleabay/dumpster-dive/etc is a nice project for the basement. I built my own mini data center in a half rack about the size of a garage freezer, keeps it all organized, quiet(er) and mobile. (wheels and other goodies, its really nice)
How many drives are you planning on? Once you break 12-15 or so, the norco (or similar, check fleabay) is the cheaper option regardless.
