Picked these up for my TRON Legacy theme build. Got the optional light bar upgrade kit(s). Note, for a quad channel package you will need two light bar kits as each covers two sticks. No issues with installation, just plug and play, like any memory should be. Do take note of the orientation of your memory slots. I put the bars on with the DOMINATOR text all flipped the same direction. The memory slots on my mobo are reversed on the opposite side of the processor, so I'll have to take the bars off and flip them. Build quality is very nice. The aluminum tops are very nicely finished. The lighted top is a nice feature.
