Take the cheapest E5 cpu, stuff maximum ram possible in it, put it in a box that does 24 hotswap SATA's and plug in a LSI host controller with 2 external ports in it. Install Solaris/Ilumos/whatever on it, turn on ZFS, create 12 mirror pairs inside RAID0 field (RAID10). Turn on deduplication and compression. On a good day you can probably put around 50Tb of data on that pool, any drive failure will initiate a rebuild of only that mirror pair, and you can expand the system (while running) with additional JBOD boxes (12 or 24 or 48 drives) filled with nice fat 3Tb drives. Theorycrafting, you can end up with about 200 drives of 3Tb for a grand total of 600Tb native space. This is pretty much cheapest setup in the world for "proper" storage. Also RAID5 rebuilds in case of drive failures are longer then RAID10. Dedup and compression should help a bit to offset the storage loss.
