My liquid cooled rig has 3mm LEDs inserted into various water blocks, fans, & clear plastic fan shrouds as well as a couple LED strips to illuminate the case. I also recently upgraded my Deathstalker Keyboard as well to the Dealthstalker Ultimate Keyboard as like the Naga Epic I can change the LED colors from Razer Synapse 2.0 Just last week I replaced/upgraded my Naga Mouse with the Naga Epic Mouse as the Epic version allows for changing the colors via Razer Synapse 2.0. My main rig has two Razer headsets (Tiamat 7.1 & Carcharias Stereo) which work well. I am a self admitted fan-boy of Razer peripherals.
