Build a better man-trap

There is a saying: If you idiot proof something, the idiots will astound you with stunning feats of inventiveness.

I am that idiot.

You see, I like to design and build things. It's part of who I am... Unfortunately right now it's cheaper to buy a pre-fab entertainment center than to buy the wood and build it myself. (Partially because right now there is a 12" mitre saw with my name on it; sitting on a store shelf somewhere... waiting for me to come up with the cash. So I would be down 500 bucks before I even got to the lumber.)

Unfortunately said prefab furniture was designed to be build on a perfectly level floor by two people inserting slot A into tab B. Unfortunately I'm one person.. and when I push my rolling chair across the floor I feel like I should have taken some dramamine first. So the edges don't line up perfectly.. Which would be an easy fix except that in order to get to the screws that are holding the offending pieces together, you have to take the whole thing apart. Since I want to play my PS2 before next week, I'm going to have to live with it..

Oh, And I'm missing a piece.
