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.
When I stopped caring about super quiet: E5 1680v2 @ 4.5Ghz, 980ti, i750 SSD - JS9500 & Dell P2715Q for dual 4k@60 because reasons
SAN shares over 56Gb infiniband, microcenter + fleabay = severe risks to my wallet
