This may be it!
I've tweaked the design a little. I've added the front bezel like I wanted, added some support underneath the plywood, and added a platform for the tower like Seti suggested. I've also removed the one side leg on the shelf, but added a 2"x2" underneath it just in case I need it.
The case I found in Google's warehouse is an Antec 1200. This *might* be the case I go with on my next rig, maybe not, I've seen some pretty good full size cases here recently that look a lot nicer IMO.
This might be the final revision, I don't know for sure yet. Let me know if you still have suggestions.
Possible invoice for parts:
Two 1/2" to 3/4" Plywood Sheet, 4'x8' (thickness depends on stock)
Fourteen 2"x4"s (Maybe more or less depending on sold length)
Some 4", 2", and 1 1/2" Screws
*NOTE* If you think I'm buying too much lumber, OH WELL! If there is any extra left over, I want it. I can use it for other things. If there isn't any left over, then fine.
This is looking like a $250 to $300 dollar project, and a long day's work.
