Gun metal gray comes with the light kit to fill the goofy gaps everyone hates. I used it for abt a yr after I gave my gf my white dominator titanium, like a dummy, and took her RAM bc she wanted a white out build after abt 6mo of pc gaming... so it has been used maybe a little more than a yr. I needed some low profile RAM so I'm just trying to lube up for the punishment I'm abt to take...
