There is enough room in the front of a p180 that you can use right angle plugs with the door closed. There is also a convenient hole at the bottom to route those cables.
That is what I do when I want front ports and want the door closed.
I've got it easy though, i can use the x-fi drivebay panel jacks, or I can use the jacks on the megaworks speaker pod.
All that said, none of that does any good if you really want to use the builtin ports with the card you've got. sorry. :-0
