I was thinking of it the other day, Just need a blank disk to make an installation CD, right? 
Windows 7 will need a blank DVD, it's a 4gig Iso I think.
 Thanks for the help chaps.



 Temps seem to reach around 59 degrees and everything seems alright 
 sooo... hmmm, not sure what the problem has been but thanks anyway guys. 
Happy to help mate, I'd still use this as an excuse to try out Windows 7 if I was you, much better than Vista if you ask me, even in RC guise!
 Thanks for the help
