Entertainment Ledge: First Drafts

So I've been considering designing a simple ledge for the living room of my roommate and I - we need a place for a water dispenser and it would be nice to have a ledge right for the blu-ray player.

Shopping List:

• 3 metal wall brackets to mount into the studs
• 1 6-foot plank of wood - at least 2 inches in thickness, 4 inches in width/depth
• 4 45” / 3’ 9” legs — idk whether they will be wood or metal yet. Probably wood?

Design:

1 square grid = 4 inches (mostly)
