hey Scott..

If you have a 3-D file of what you need for the side of your computer side panel, you should try to export the file in an .igs format file to be imported into Autocad for CNC toolpath.

I believe that you can't really laser cut through ABS plastic. I think it gumms up during the cut which leaves you with crappy results. I've consulted with Tap plastics about this when I was researching ways to cut my abs grill kit out. You might have better results with water-jet cutting but not much. The other option, if your heat is set in laser cutting, is acrylic. Keep in mind that acrylic has different characteristics than ABS in terms of durability, heat resistance, and finish results both good and bad depending on what's important to you.

However, if you do go with water-jet, may want to consider a stain-less steel designed cover. The results are very good and the finish is chrome-like. That's how I did my stainless steel grills. Good luck with you decision and quests.
