if you're going for a white motive, imo the corsair dominator sticks look kinda ok, and some of them have white leds
g.skill tridents are also made with a white/brushed metal finish
there are creamyish white ballistix sports sticks
also there are atleast ddr3 sticks of hyperx in white, but i couldnt find any ddr4, in stock atleast
for cooling, you cant go wrong with heatsink, just get a bigger one than that c7 sff if youre going to overclock, you can put any white fan on one to make it fit if you care enough
or if you care too much, theres an aio with an all white motive, radiator, pump and fans. deepcool gamer storm captain 240ex, didnt find anything too damning about it
