hello, i plan on purchasing the new mac mini solo. im kinda on a low budget so im going to need some help. im just the normal user , i dont use anything like photoshop. im not sure what i should upgrade when i order it. i think i should upgrade the ram but its $100, im thinking of ugrading from a 60 to a 80 gb hd for only $50, and im dont think i need the superdrive, thankyou and if you could suggest to me what i could get, i would realy appreciate it
