Don't you want to build it your self?

You can buy a premade cabinet... but you're still going to need to hack it, cut it, saw it, drill it, tape it, bend it, push it, pull it, bang it, test it, remove it, re-install it, and hammer it.

If you build it yourself you can save $ (IMO), and you can have it custome made to EXACTLY what you need/want.

What you say? No? Need to buy one?
