I finally got around to posting a pic of my cabinet. This is a follow-up to some threads from a few months ago about homemade cabs - I wanted to post all of the details as an example of one direction a person can take. I have a few other shots I can post if anyone is interested.

I bought the 12" Line 6 Modeling speaker used off of Ebay (about $30).

This is an open-back design, 3/4" Baltic Birch, butt-joints (glued, pneumatic nails and glued/screwed wood bracing. The edges were routed with a 3/8 (or 1/4"?) bit - the funky joints on the front were just done with a pad sander.

The inside was spray painted with flat black. I used truck bed liner "paint" for the exterior - I used a textured plastic roller to give it.... texture. This stuff is really durable, but plasticy feeling, so I went over it with a rubber spray coating to give it a more tactile feel. The handle, corners and rubber feet were obtained locally from SLM (now owned by Loud) - these are replacement pieces for the old Ampeg Paraflex amps.

The speaker cloth is camo-burlap mounted to a 1/4 ply board. The speaker is then screwed through this board and into the main soundboard. The speaker is wired to a standard 1/4" female jack mounted on the rear cross piece. All connections are soldered.

The main reason I built this was to give my Trademark 10 something beefier to push. It sounds A LOT better than the little mini-speaker in the Trademark and A LOT louder. What's cool is that I can leave this cab at church (my gig :-) and bring home the Trademark if needed.

I think I have around $100 in the cab and $30 in the speaker. IMHO it was worth every penny. It's very light, should be fairly durable and it fits my Trademark perfectly (cause I designed the thing so I can keep the Trademark on top).

I think it took about 2 weeks to built - 10 hours total? It's been in use for about two months now - from the pic you can see it's been hit with the basket balls several times and just has scuff marks - the truck bed coating seems to be holding up well. A direct hit to the middle of the speaker might not be so good...

Anyway, just wanted to share.
