Hello, i am planning on building a new pc within the next 2 months. I already had most of the parts that i wanted picked out. However, since i am on a budget, i was wondering if i might be able to reuse an old hard drive from my current computer. The harddrive is 1tb 5400rpm and is from a gateway computer. It also has windows 7 and i already needed an os for my new computer. So in conclusion is it possible for me to do this? Thanks
