I need a bigger case? What could possibly be larger than a haf x?
I would stay away from koolance, they've always had quality control issues, lately EK's been having nickle plating fall off too
I've never had any problems like that with the Koolance kit I have owned and I've built quite a few loop in multiple machines. What products are those photos taken from?
I find it pretty strange as I use Koolance pretty much exclusively (where possible), due to their higher level of quality.
In reality however, when it comes to gpu blocks, all the products from various manufacturers offer pretty much the same performance.
