I was planning on putting my 7200 RPM 320GB Scorpio Black Hard drive in the new MacBook but the first thing I noticed when I did was the vibration was rediculous. I didn't have this problem with the Macbook Pro I took it out of.. Its looking to me like its a result of the way they mfg. such a stiff case. Hopefully theirs some kind of mod that will keep the vibration down... I love the new design. Anybody else tried it yet and had different results?
