I'm upgrading my Infrant fileserver at home from an old X6 box with 4x250GB disks to a new NV+ box with 4x750GB disks. The X6, by itself, is pretty much worthless when you can get a new diskless NV+ for $600 or so (and with much, much lower noise), but the disks (Seagate ST3250823AS 250GB SATA drives) still have some value. The question is what I should do with them. Cheap USB/Firewire enclosures? eBay?
