My Kenwood hi-fi which serves as my computer's speakers through aux , bought with savings from my first job, in McDonalds, 1997. The LED display is a bit faded though. I'll be sad when it dies.
My cheapo Chicony PS/2 keyboard, bought in 1999. Occasionally I use some contact cleaner spray to clean it up, apart from that, some of the letters are showing subtle signs of wear. I wonder how many words I've typed on it.
People are mentioning desks. My parents gave me my computer desk. It might be as old as I am, not sure.
