Darby darbysgoodies at gmail.comDarby, I apologize for the delayed answer - I was traveling to US to do more demonstrations of UmTRX. No worries, Im sure youre a busy guy -especially at this stage of the project =) I'm not sure whether you actually need a 3D design here? As I see it, > you select a proper existing case and just design front/rear panels > and drilling pattern for mounting. I may be wrong, though - I've never > done this before. I just worry that a fully custom case could be too > expensive in small quantities. Im sure you could use a preexisting design, and just punch some holes in the sides for convection cooling, then punch some holes in the back to accommodate power & cabling, and use some motherboard standoffs that would keep the board mounted in place on the enclosure floor. I was thinking more along the lines of stamped/bent sheet metal, some lightpipes (plexyglass or polycarbonate) in the front so youve got visibility of the lights in the front & some countersunk holes on the sides to keep the 2 C shaped (or L shaped would work well too? -Which might be a better implementation for mounting purposes if youre going with lightpipes as opposed to holes in the case for lights) pieces bolted together & a powdercoated or painted finish? I found some design tools at protocase, that it looks as though will pushout 3d cad files as deliverables, but looking thru the project files -I cant seem to find anything that would give me specifics on distances between the mounting holes from each other's centerpoints & how wide these holes are, If someone can point me to a place where I can find this -Ill take a stab at case design when Ive got some free time... =) On a side note, They also have an extruded aluminum offering (http://www.protocase.com/products/index.php?e=Aluminum) where the sides are the same between the left & the right, with a fixed height of 1.72" (43.688mm). For mounting they use some internal channels that the board will slide into (as opposed to motherboard standoffs as suggested above) then they use a sheetmetal bridge for the top & bottom to determine the width & then sheetmetal on front & back as well -Depending on quantity, they might be willing to sell lengths (like say 10 or 20ft at a time) that your people could cut to size & fabricate their own top/bottom/front/back panels? Just a thought...
