Okay, fixed the majority of the problems with the script (main problem: something possessed me to use all 'center = true' flags which made everything much more difficult)

Anyway, fixed and updated now.

Supports PSU spot generation (at bottom, fliping of PSU screw spots availible), PCI card slot generation (no brace yet) backpanel generation, and extra spacing.

Future plans:
-Dedicated parametric fan hole cutters
-HDD holder, CD drive slot
-Front panel slots/lights (should be simple.)

Warn. I think my ATX screw locations may be off, but I have no way of testing.

Do one of the following:
A: Render, cut apart and print.
B: Use as guide for other material.
C: Iunno, cut mesh into flat surfaces and use for lasercutting.
