Both Shaun and I have 3 bay N0503 boxes from Thecus. You can get them from Scan for £274, although they do not come with disks (which are cheap enough). They also have dual Gb NIC's which is handy for WAN/LAN operation, iSCSI and a great user interface. And in 3 years of solid running it hasn't stuttered even once, not to mention that Thecus keep up firmware development way beyond when other manufacturers call it a day on their models. Oh! And it's silent!!
