I started my build last weekend.
My cabinet is based on the Jakobud Moon Patrol drawings.
To me, the Williams cabs just look 'right', and I prefer the cutaway look of the front on the Moon Patrol cab to the straight sided Robotron style.
While I was discussing cabinet shapes with my wife, we came across the awesome 'Blip' made by markc74.
Once my wife saw that black cabinet with white T-molding and buttons, it was game over.
Markc74, if you read this, please don't be mad that I copied your color scheme, my wife made me do it

I made the cabinet 24" wide between the sides, so it is 25.5" wide in total.
The wood is 3/4" maple veneer plywood.
It's more expensive than MDF, but it is stronger and lighter.
Lighter is important, because I currently rent an apartment, so it is inevitable that I will have to move it at some point.
The plywood was nice and flat, and the high quality veneer was smooth enough to paint.
My goal was to get the sides cut and the battens attached, but the work went quicker than I expected, and I managed to get the whole frame cut and assembled.
I did the whole thing with a jigsaw and a trim router (for the T-molding slot).
It would have been easier with a circular saw and a full-size router, but I think some of the horror stories have been exaggerated somewhat.
For instance, I had no trouble getting straight lines with the jigsaw, and my cuts ended up square, despite all the warnings about blade flex that I read.
The slot cutting was shockingly easy.
My trim router's manual shows slotting cutters as optional accessories, so I didn't pay too much attention to the warnings about trim routers not being powerful enough.
I had been a little apprehensive about cutting the slots because I had never used a router before.
I did so much research that it was a complete anticlimax when I started cutting.
I tried it out on a piece of scrap first, got the blade adjusted to the center of the wood, and had the whole thing done in three minutes

I didn't take photos during the building process but here are a couple of (terrible) photos of the assembled cabinet.
After assembly:

Two coats of paint and coin door fitted:

(I'm aware that the speakers are in backwards - I just put them in the holes to keep them out of reach of my inquisitive 5 year old daughter

)
I'm going to try to get the T-molding fitted tonight, and hopefully get started on the control panel this weekend.
