I think I really like Pandora.  I've started collecting stuff for the 
proposal in a folder named "HPSDR Pandora."  ;)

Got it - looks great!  I need to study it more and compare to the other 
drawing.

We may need to have a poll on the orientation.

I'll admit, I'm split three ways.  I'd love to have cables where I can 
easily get at them (on the front panel), yet I like the idea of a clean 
front with nothing on it maybe save for a power switch, while at the 
same time I like the idea of keeping the front panel open for LCD 
displays, switches, meters, etc...

I wholeheartedly agree!  Send your wishes and I'll compile.

Absolutely on both counts!

The design must be troubleshooting and modification friendly.  Hinged 
and/or easily removed tops are a must.

A removable, flat front panel is another must have to allow easy 
modifications/additions.

Ideally, I'd like to put together some slick solid models outputted to 
PDF.  I say "ideally," as my current efforts to date with solid models 
and lighting/shadows/etc have not been all that "slick."

We could always start a Yahoo Group as a files/photo storage area, or 
perhaps this is the perfect opportunity for me to rehab my QTH.net 
webpage...
