If it came with 90 headers, kind of like a car alarm module, and all I had to do was plug in some straight connectors on the side, that would be easiest for me. If I found some 90 plugs or made some up, that would be easier for you. But either way, really. Straight connectors going up in the 'z' direction tend to make the component have a considerably larger "installed volume".
Edit: Funny thing, I just realized I was (probably subconciously) trying to encourage you guys to make your product look like that other inferior, overpriced box of transistors mentioned earlier. I don't know, I'm sure you guys will make the final product clean and functional, so no gripes, just an idea...albeit unoriginal.
