A (chain of) clothes store had amp cabs in their window a few weeks ago when I walked past. When I walked past the second time I thought, hmmm... those would make perfect project cabs, so I went inside and asked if I could perhaps have one or more of those when they'd taken them down. They said "well, we're not allowed to ... but it seems a shame to throw them away. So as long as you don't use them for advertising we'll let you have some, how many would you want?" I could only reply "how many would you let me have?". Well a few days ago I picked them up. Here they are.
They're actually quite nice. MDF boards for sure, but quite sturdy. Here's the front panel for the little kind.

And the large one.

An inside shot.

I reached in to the cabs when they were in the shop window and could feel that there were in fact pots behind the knobs and that the on/off switch could be flipped, promising i thought.
As it turns out there were pots. I've just opened one large and one small, the large one had all C50K (reverse log, that is) pots and the small one had all C20K pots. So if someone knows a bunch of projects using reverse audio pots I'm interested to know about them

The on/off switch looks as a real switch (haven't tested it yet), but the jacks were the big surprise. I kind of expected them to be mono jacks as I thought they'd stuff the cheapest possible stuff in there, turns out I was one for two.

WTF!
They have actually bothered to find jacks without any connectors at all

Well, at least I have a bunch of spare nuts.
I've actually managed to mount a speaker and a Marshall 8010 curciut in one of the small cabs (were actually in the process of building one when I first saw these cabs in that shop window

), no pictures yet, I'll post those when I've taken them. Sounds good, the control panel needs to be pinned down a little to stop the distortion that it gives right now, but on the whole I'm more than satisfied with the result.
