...is there I anything I should know in advance? I've already got a Torx screwdriver. Looking to get this hdd (I'll visit the store on the way), I assume it's compatible; http://www.microdirect.co.uk/(39586)Western-Digital-500GB-25-inch-5400rpm-8MB.aspx I would get a 7200 but they don't seem that easily obtainable. I can always slap the 500gb in my PS3 if I choose to put a faster one in at a later stage. I can't wait! My current comp is a 2 y/o macbook which I plan on using kind of like a mini, permanently hooked up to a 24" monitor in the study. Which actually brings me to another question - given that my old mb will permanently be used as a desktop, should I take out the battery? I know cpu cycles take a hit but as it will be used purely for browsing and torrents, would it make much difference?
