[sdiy] Front Panel Express Template question

[synth at oldmail.charlielamm.com]

I am considering getting rid of all my frackrack stuff and going with a 
different solution.  

My current thought is to buy some sort of rack enclosure (like a 2u one
from sescom--http://www.sescom.com/enclosures/rack_chassis.html) and then
substitute a front panel express front panel for the one sescom supplies.

What I am afraid of is not providing FP Express with the correct
dimensions for the front panel, and ending up with something expensive
that doesn't work with the rest of the sheet metal.
  
Does anyone know of any templates for this--a starting point for FPE's
software that will allow me to create front panels for rack mountable
enclosures where the front panel is correctly sized and drilled for the
rest of case and standard 19" rack rails?  

Or do I just have to buy the sescom or equiv. stuff and take really
careful measurements?

(I am not married to sescom BTW.  If anyone knows of some "Front Panel 
Express Ready" rack enclosures and templates I'd love to hear about it.)

Thanks.
