Reply to VCI-100 Internal Space - Sound Card?

Hey All,
If memory serves, Ean mentioned that there is a lot of room inside the VCI-100. If thats the case, I want to put a sound card inside the thing. I am assuming all the ports will need to be removed from the sound card and placed in the VCI where permitting. Some questions before I start.

1) Is the echo the smallest card out there?
2) how much room is there in the VCI?
3) Anyone done this before?

Thanks,
Joe
