I dug up the model number of the Keyboard, it's a HP5302H. I love the volume dial on it, so wish at least some keyboards these days incorporated such a dial. Very nifty to have one.
That rig makes me nostalgic, it makes me remember my old rig. College days... part time job and saving up money to build a PC capable of running games that I wanted to play. Good ol' days. Life was sweet back then. Thanks for posting the photos mate!
