OK, I have quite a few fibreglass cabinets ideal for MAME builds. They come with doors that are lockable (which I will provide the key for) and built in wooden shelves for the monitor.
Here's an
almost complete cabinet I built from one a couple of years ago. I'm not sure I ever took a pic of the finished cab!



These also make good cabinets for jukeboxes.
For £75 you get one fibreglass cabinet, unpainted (they come in beige and have a nice 'candy cab' feel to them. These are hardwearing yet light cabinets. They are also a decent size - not too big, not too small. If you need anymore details give me a shout.
Any interest please PM because I'm not always checking on the forum.
I'm located in Norfolk, UK and anyone interested must collect. Cash on collection please.
Also, I might add that if you require kits to make these up fully (joysticks, buttons, wiring harnesses, but no PCs) then I have quite a few of those available too. These can be purchased at actual cost rates as these are surplus to my requirements (just thought I'd offer the option as I know how eager some people are with starting projects!
