Just built mine and it's great - but my hard disk is labelled H:, with removable drives taking up the earlier letters. If I disconnect the 6 in 1 card reader and reinstall XP, will my HD then be C:? It would be much more convenient.
Apart from that, I'm very happy with it, although I wish I'd realised it had S-ATA sooner - those IDE cables are incredibly bulky in those small cases!
