My son has given me 3 IDE Removable Caddy enclosures. If you don't know what I mean, take a look at these item numbers in ebay - 370480425397 or 320605837171

They don't come with drives but they're free if anybody wants them. They're white unlike one of the items I've listed and don't have fans.

I'm in Wymondham if that helps but I do come into Norwich on occasions.
