Source(s) for large project boxes for external crossovers (

I want to move my crossovers into external enclosures, but I can't find any ABS or polycarbonate project boxes that are large enough. I've found some industrial-type enclosures, but the prices are ridiculous.
The PCBs are 16" x 10", and a few components stand about 3-1/2 inches in height. I'd like to have a little extra room so something a minimum of 18" x11", and at least 4" deep, would be ideal.

North Creek Music had some big enclosures for their B&W 801/802 crossovers, so something similar to those.

Wood box is how I'm leaning since I can't find really find what I like without a ridiculous price. I've seen some wooden wine crates online that are about the perfect size; they don't have lids, but it would be easy to cut something to fit. I'll probably just end up making a trip to Menards and firing up the table saw to make my own boxes.

Sometimes Hobby Lobby, Michaels, or Joann have bamboo drawer organizers or the like that are pretty good (might take two, one flipped on top). I used some $5 ones for little parts express amps for my sister's kids.

They have pine/white-wood boxes too, but they are generally crappy enough you'd be better off making those yourself.
