I have an old Core 2 PC, no longer worth using. Took the side off it, and
saw crappy old graphics card, so dragged it into the garage for trip to
recycling yard. But my partner advised me this was a PC she got from a
former workplace that shut down, and it had extra disk drives in it.
So looked again: this case has slide-out disk cages that pretty much hide
what is in them. Apart from the active drive (32OGB), it had two 1TB black
drives, unplugged, and apparently unused.
