I love my corner desk:

I bought it about a year ago (saved around $150 from this price to pick it up in-store and do the delivery & install myself), and it easily fits 3 large LCDs and my PS3. I like the fact that if I need more space later, I can add side desks to it - one of the benefits of expandable office furniture. There's an optional keyboard tray, but I like having my keyboard/mouse on top of the desk.

I'll probably custom-build my next desk.. I've been kicking some ideas around of a wood framed, glass-topped desk that actually contains the internals of 2-3 computers. I'm still working on the design to isolate sound and vibration from the machines, while still having them be viewable through the desktop glass.
