The desk I'm sitting at was purchased in 1998 at Staples. It's vaguely triangular so it fits in a corner, and, while it has shelving to the left and right, it is open at the back to fit a CRT. Sadly, my widescreen monitor can't fit back in the hole. The desk also has a broad keyboard/mouse panel that slides out on rollers.
This is either a testament to the quality of Staples' furniture selection in the '90s or proof that I'm the cheapest man on Earth.
