Hello Edward,
I am the lead software developer for Protocase. We actually would like to save other formats but our primary goal is to give our customers free software that makes designing and ordering enclosures easy. We will eventually export to Solidworks format at a minimum, and possibly IGS or some other open format.
We have just started adding computer enclosures. Traditionally, people are not willing to pay custom prices for them (about $200 to $400), as mass production prices are so much cheaper. However that seems to be changing so we are adding support as we find the time. Since we are a sheet metal company, not a computer enclosure company, could you provide a link to a SFX PSU you would like to see us have a mounting bracket for? I will personally make sure we get it added. We will eventually add mATX as well if uptake on the ATX and mini-ITX cases is good.
Sincerely,
--Douglas Ronne
