Here are some instructions to open the lid on the Quark just in case others are trying to open their case as welll:

Best way to remove the lid is to stick a small sharp screwdiver above the "R" on the plastic lid where it says "MONSTER" (there is a small notch cut out in that spot you will see) gently pry the side of the aluminum case outward just enough to then pop the plastic lid upward. Works very well.
