Quick change that could make your loop look a lot cleaner. Change the outlet of the gpu, so both tubings are on the upper part, that way no tubing goes down and up again, it should look at lot cleaner.
If they re-make BF3 maps for BF4, I'd be VERY mad at DICE for not bringing Seine Crossing AND Grand Bazaar. Those two are a MUST if they're planning on bringing more BF3 maps!
Probably Strike at Karkand too, but that's a BF2 map, not sure they'd do that, but it would be AWESOME, best 3 maps ever.
I know it's not EK's fault here, but with some nickel plating already off the block, pretty sure it will keep growing and growing and more nickel plating will get off the copper, making it a lot worse. Once that process starts, don't think you can stop it.
