Hello all, new here to this forum. I was wondering if this is a compatible harddrive http://www.amazon.com/Western-Digit...J5OG/ref=sr_1_1?ie=UTF8&qid=1300929505&sr=8-1 and if this is compatible 8gb ram http://www.amazon.com/Memory-MacBoo...?ie=UTF8&s=electronics&qid=1300929734&sr=1-11 I am making a switch from PC to MAC, I am also going to install these myself when I order my i5 13' next week.. the cheapest base model is all I can afford or do you guys suggest I save and get the $1499 i7?? I like the size and portability of the 13'. I will not buy solid state drives because it's too expensive right now.. Do you guys recommend something else brands as far as HD and Ram goes.. also what site are good to buy from besides amazon? Thanks so much for your time and reply.
