I have found when dealing with both older and off brand PC’s that Amazon is the place to shop. If its a new keyboard for a laptop or a video card for a desktop that needs replacing Amazon is Fast accurate and inexpensive solution to find these obscure parts. More big chain office supply and electronics retailers are getting away from stocking PC Components due both to how fast they become obsolete but also to the quickly changing prices. You can always shop the latest price deals on both OEM computer hardware and software as well as upgrade items take a look at what Amazon has to offer before you buy elsewhere.
