A 2" X 2" would be sufficient. Be sure to screw it to each wall stud and screw the top to the 2X2 about every 16". Reason is, the type of angle brace you want to use for legs will push top out from the wall.

will do! But I'll probably screw it in every foot or so -- Ms. Belt & Suspenders that I am. Thanks

Gina, my DH is working on a similar project for our sewing/computer room. He's making a set of 3 tables that can be moved around into different configurations. There is room under the tables for rolling carts we picked up at Office Depot. Since they are individual tables, I can move them where I need them for the current project.

Have fun building yours!

I suggest you consider ways to move the following items OFF the desktop.

printers, scanner, camera dock.

The more you put on that desktop, the less working space you'll have. And working space is actually at a premium.

We have our scanner on a shelf

You could wall-mount the camera dock, perhaps (or install a shallow shelf on the "backsplash" area of the desk to set it on). A wall mount might be a good way to handle some future gizmo's, too--back-up external hard drive, PDA dock, etc. The smallish ones.

Lots of times printers are shown on low carts that roll under--if you can find a way to preserve some "roll it under" space w/ that desk, that might be really useful.

I wish I could suggest how to brace that corner without blocking it up completely.
