The nature of there being different versions of the Eisblock XPX (different tops, mostly) means that Alphacool saw the potential for increased modding and decided to offer first-party solutions to scratch the customization itch. If you have the original versions with the metal frame cover on a plastic top, for example, you can get a modding kit consisting of a differently colored cover, a tool to help remove the stock cover, and four differently colored inserts that get backlit. Given this particular nylon top version can't really use these, I moved on to the other accessory they sent over, which is a set of replacement locking collars for their compression fittings I used on the previous page. I chose the same blue color as the other accessories that come in the modding kit—namely, more rubber covers and screw caps in that very color and Intel/AMD mounting brackets anodized in the matching color. This makes for a nice kit that can be as blue (other colors are available) as you want.
Given the nylon top versions do not have an LED integrated to backlight the aforementioned insert, Alphacool instead offers two different frames as part of their Aurora RGB product lineup that go around the Eisblock XPX snugly. One has a polished chrome finish, while the other has a rubberized black finish, and both have the Alphacool logo as well as several RGB LEDs on the inside directed to shine light into the block when installed. A 12 V, 4-pin RGB LED cable comes out the side of these frames and can be connected to any compatible LED header for control. These are not addressable digital RGB LEDs that operate off a 5 V/3-pin header, so be sure before you short anything accidentally.
Here is a look at the block lit up via the frame, which provides for a powerful light show due to its many LEDs and supports static and dynamic lighting effects alike.
