Here's the Mod i did on my Cooler Master case this early summer.
It is not entirely finished, it needs some very thin black plastic borders to make it more clean and perhaps will put Case Handles on the side tops, but got not so many spare place to place the screw holes.
The Acrylic glass is Skyblue color and 3mm thick, and now the dual-fan have blue leds...I've also wired in blue most of the inside cables.
Took me times to clean-up the dust of metal (of course the case was empty)! It is hand-made for the open space.
