de-casing Compaq DeskPro?!

I have this damn deskpro that I finally removed the mobo tray from (that was one piece of work! i had to use my feet to push on the case to remove it!). Anyways, I am de-casing the whole thing and ran into this problem. While taking out the "hinged drive case" I found a cable that ran to some small box shaped item. It looks like its grounding, but I can't remove it do to the odd screws. Not only that, but its wired up to a cable that I need to connect to the mobo so the power button works. What should I do?

I'm sorry I can't take a picture, someone had my digital camera right now...

Anyone?!

I believe the screws Compaq uses are Torx fasteners. If you don't have the right screwdrivers, an allen wrench of the correct size should work, or if you're really desperate, a small flat bladed screwdriver may just do the trick.
