That kind of cover would look nice if it fits. But, what I did with my Shuttle SB51g is stealth the drive by moving it further back in the drive cage. Then i sawed off the bolts in the back of the cover for the empty bay, and glued it to the drive tray. This looks very nice, and you can still see the access light b/c the cover is translucent!
Who uses that headphone jack anyway?
The best part: its all FREE!
I'll post a pic soon, but my digicam is broke.
