I have an old IBM Thinkpad. I don't recall the model right now, but in is a 12GB Hard Drive. As I plan building this laptop, I keep wanting to upgrade the parts I'm planning on buying. So, to counter this, I thought I could put this drive in to save a little coin. I figure if I skimp on the hard drive, it's easier for me to justify buying a Gig-o-RAM instead of just 512.

Would there be anything stopping me from doing this? I assume it just a regular 2.5" IDE Drive in there, but I don't know this for certain.
