Century has been selling the Tera Tower in Japan for a while, and it can contain 8 3.5″ IDE or SATA HDD’s. The Tera Tower connects through USB 2.0 (Why not via FireWire or eSATA btw?). You can slide in any HDD you want, so you can combine a 120GB with a 250Gb and a 80GB HDD for example. You can also play with the partitions and create 8 columes, 1 single volume or 2 volumes (7+1, 5+3).
