I'm looking to buy a laptop riser (stand) for installation in a DJ booth. My question is how tall is the front end of the Griffin iCurve. Specifically, how much room from the surface of the table to the bottom of the plastic in front (how much clearance)? Thanks in advance for any replies, this kind of dimension isn't advertised anywhere. All i can find online is the maximum height in the back (6 inches). cheers!
