My pc is already built, the problem is with upgrading ram, i already have ram HyperX Beast on the first 2 slots, so in order to put another 2x hyperx beast on the last slots, it comes right under the latest fan so i have either to move up a little the fan or move it to the left, so rather doing that, i decided to sell my 2x hyper x beast and buy all 4 kits of hyperx savage 32 gb ddr3 2400mhz.
