On sale! (normally $39) The Alphacool GPX SLI Connector Plexi Edition is designed to be the connecting link between your Alphacool GPX waterblocks and can also use LEDs to light up the Plexiglas.

Installation is very simple. The special connections have 1/4in threads on one side and just a straight piece of pipe on the other, which is simply plugged only into the SLI bridge (double O-ring). This allows the installation to be done even if the coolers are mounted.
