Right, got all my media center components delivered now - ready for a weekend build! A big thank you to everyone who helped me make decisions by the way. Just been reading through the motherboard instructions whilst "working from home" and it said that i must install windows XP before using a SATA hard disk! Now, only just about being confident enough to build the machine myself (with a little help from friends if necessary) this has confused the hell out of me. What am i meant to do?
