Besides using WD 500GB models, are the WD 640GB and WD 750GB (the 9.5mm thickness model) good to go for? I am still considering as I have heard from other websites on the computer does not draw enough power to power up the 640 and 750 as it has the clicking sound and the rainbow keeps appearing. Anyone has install one before yet?
Please advice. Appreciated! Thanks a million to all the Mac gurus out there!
