Other than that though, for a 6800k + 1080, you should probably get at least a 360 rad, preferably more. In the x71, you might go with a 360 at the top, plus one in the basement. I would then pick up a DDC pump, a Reservoir, and for fittings, a minimum of 2 compression fittings per component. From there, you might want to get an idea of what direction you want your pipes to run, and choose right angle fittings accordingly. Then, you'll need a drain at the bottom, so I'd pick up a T-fitting, a rotary straight male-male fitting, and a ball valve drain port. I personally have a similar setup to this, and also included a temp sensor, since they act as a plug for empty slots anyway and only cost like... $10.
