It'll be interesting to see what you ultimately end up doing with them. But yeah, the mirrors alone are worth the $20! I just looked at one today, but it wasn't a DLP based machine so I passed on it. On the other hand, it occurred to me later that the cabinets contain a LOT of plastic. If the plastic could be made into usable FFF filament... Whoa! That would be amazing!
One other thing I thought of, though unrelated, lets say I picked one up for free, of any type. I already have a big plasma TV so there would be nowhere to put it inside, but what about outside?
Like, have an outdoor theater in the the backyard for those nice summer evenings. Something like a barbecue cover could be used to keep it waterproof when not in use.

Especially if I could find a free one!
As for UV, one could try converting to LED.

Only issue I can see with the actual use of the projector is the bulbs in these are usually under 150watts, not sure that would be enough for most resins.
BTW found 2 in town just now with toasted color wheels 720p, for $20 for the pair. lol

Problem is, THEY'RE HUGE!
You need help loading them. They only weigh around 80 to 120 pounds, but they are usually too big and awkward to just pick up and carry for one person. And I doubt anyone would let you take a chainsaw to one to cut the projector out! Here are some examples from around Los Angeles and Las Vegas for under $100:
These are a few in the $100 range but, I'll bet if one looked around hard enough you can even find these for free!
