Upgraded internal HDD for the 630
For those of you wondering if you can upgrade the hard drive the answer is yes. I put a 1TB 2.5" hard drive in one of my 630's today. It is a little taller (12.5mm) than the normal 2.5" hard drives but there is room for it with about 2 mm to spare.
For those wondering what drive I put in it was a SAMSUNG HM100UI. It gave me 140 hours of HD now.
