Had some fun with the laser cutter at work.
First made a custom front panel for a Synthrotek Echo a few weeks ago:
I've also been planning (in my head) on building a custom case using laser cut acrylic.
Bought some Tip Top Z-rails and made this 12u 84hp beauty. Still waiting on one more set of z-rails and another uZeus.
I'll post the Illustrator files I used to make the case. The acrylic panels lock together with finger slots and some acrylic glue. I made the box using http://www.makercase.com/
