Yeah the HDD was already installed when I got it, and still has a bunch of files, programs, and games - including several docs people were apparently in the middle of. Hope no one needed these. I can remember my mind being blown as a teenager when I got this and found Microsoft Word, Microsoft Office, and Super Paint all instaled. As well as classic Sim City, though it's copy protected. I've never opened it before so I don't know what kind of HDD they installed, but considering it seems to have been used a fair amount before I got it, I would think it's okay?

Anyway, I'll pick up another can of compressed air and see about opening it (carefully) and spraying out the dust. Hopefully that will do the trick. Thanks for the help guys.
