Hi all, I'm REALLY new to the world of Mac's So I'm trying to get up to speed(This will be my first Mac) I purchased from a friend of mine a MBA A1304(late 2008 I believe). I'n not sure if it's the 1.6 or 1.86Ghz machine. It needs a battery and a hard drive. It will boot via thumb drive, so I have confidence the MB is good. My main question is about getting a new hard drive for it. Ideally, I would love to be able to install a Western Digital Scorpio WD3200BEVT 320GB 5400 RPM SATA(which I already have). Will it work in this machine? Or am I going to have to take another route? I'm getting a GREAT deal on it(or at least I think I am). I'm paying $100 for it. Thanks in advance for any input Edit** Oh yeah, I will need to get the OS too, will Lion work well in this machine? Or Snow Leopard? Any advice?
