I finished a couple months ago but never got around to a final post:

The laser, water mini-fridge water cooler, and computer running EMC2 control software. I vent outdoors through a panel wedged in the sliding door. I can't do anything permanent because I'm in an apartment.

I put a front panel across the front of the fridge and then just used some plastic sheet to waterproof it. The water stays cool enough.

Don't do what I did! Perforated sheet metal has too much surface area and the laser beam reflects diffusely and burns the backside of whatever you're cutting. I'll eventually get some aluminum egg crate.

Since I did the electrical stuff without a PCB, I just used switches, but a PCB would be nice for automatic pump, air, and exhaust control. But this was simpler and got me going faster.

Anyway, I learned a lot and am slowly planning my second one of my own design.
