Basically I'm getting a new Head Unit ( http://www.caraudiodirect.co.uk/alpine-cde-9882ri.html ) for my car with rear USB connection. I chose this drive: http://www.misco.co.uk/applications/Sea ... CatId=2269 a 250Gb model to store my music on because it can be powered by USB and I thinks it's just a single platter, the enclosure will have to be aluminium as it will dissipate any heat faster and one which only needs 1 USB socket/plug. Can you guys recommend any? Not looking for anything too extravagant just a simple one as long as it's aluminium.
