pics of how it'll probably look
i have pics of how trans am's mobo will probably look if installed in btx fashion on this thread:

i think the only problem to worry about is whether there is enough room in the case for the slack in the evap hose to fit when the case door is closed. i love the btx format even aside from the theoretical cooling benefits. 1 added benefit that i didn't forsee is that i can mount my bga ramsinks on the vga card without using epoxy with just gravity + thermal paste to hold the ramsinks down onto the video card. 1 minor disadvantage is that when you read the diagnostic led pci bracket, you have to remember it's upside down.
EDIT: having trouble connecting to imageshack so just wait a little bit to see the pictures in that thread.
