dude i would go with the first one, mainly as u get an extra 100mhzs cpu power! lol not much but its a consideration, also with the firist one you get a dvd-rom drive that comes with it to. The second one would not be my first choice as it only has 17 gig space on it which isnt alot! dont fall into the same trap as me when i thought my 30gig hd would be ok and it really isnt :< hope you decide soon!
kind regards tom
