You should have a ide cable for the hard drive, might be sata, but everything should run ok, just make sure everything is compatable.
And with the parts you plan on keeping, its sounding like it would be.
The vid card in a retail computer is probobly PCI, same with the tuner card, and the hard drive (as i said before) is probobly IDE so that will just plug right in too, and it should boot windows for you.
The only problem that you might run into are the video drivers, which are usually on your hard drive, but may conflict with the new motherboards PCI ports.
