Has anyone ever converted Big case CAD files as STL files? I am considering option if i print case or do i use same what most DIY builders are doing and purchase mini-ATX case.
I know files location and i have them but online converters what i tried to use dont make printanble result and i do not have knowledge enough in CAD programs to edit them.
I need a metal case drawing 
You can find link to both 320 and 480/720W PSU models here

CAD drawings are CAD drawings so it doesnt matter if it is metal or acryl.
I decited to go on with ATX case i have so i put NDR480 and boards there.
