putting a cabinet together

I've just spent hours putting this cabinet together.  It was a deal.  I saw it on clearance when I was at Office Depot.  When I checked out, the price on it was $20.  What a deal.  It's not solid wood and the veneer on it is really cheap, but it's better than plastic.  I got it to replace a 3-bin stacking plastic rack whose wheels keep falling off.

I've put a lot of stuff together, but this one was a doozy.  Now I'm tired.
