Get an eSATA enclosure that has room for 8 or 10 drives and just connect it to box? My recommendation is the 2nd option. I ran the first for a couple of years and was always suffering disk failures because you really really need good air-flow to keep that many disks cool. I recently got a Sans Digital TowerRAID TR8M-B - 8 Bay SATA to eSATA; this shows up as two buses on the PC (which CentOS sees nicely) with 4 devices on each bus and I can run RAID5 and LVM on the disks as normal.
