First, i cant program a VCR. That said, once i found out how amazingly simple and relatively cheap it is to build a PC, I undertook the project. Using virtually free (rebate) parts,and the only major expenditure being the memory and the CPU, I have a couple of questions. Can I take the 2nd harddrive from my current pC-the harddrive that backs up all my files- and install it into the new computer and have everything as it is now on my current PC ? Including the OS?
