Does anybody have CAD (.dwg preferably) templates for any computer parts? I'm designing a case and will need pretty precise screw locations or people will be very unhappy 
I'm mainly after 15mm and old PA templates and pump screw locations. I've measured 5.25, 3.5 and 2.5" devices and the PSU but that leaves a .25mm inaccuracy.
