Many of the experienced WC's say to just use zippies unless you care about looks. Cheaper always works for me, and you can always get colored zip's to match case/mobo colors if want.
Cool; I zipped up the connectors then noticed the plastic tightener that came with one of the parts wasn't that tight so zipped that as well.
So big update: So far so good on the case build. I ran it for 24 hours to check for leaks, it was fine, so I began to assemble the components last night. So far I have spent close to 10 hours on this project, mostly because I don't want to make a mistake at any point so have tried to be very meticulous (plus my working conditions aren't that great - basically a foldout card table in my apartment LOL). Probably the longest time I have spent on a computer build so far, but it's fun getting into the whole water cooling scene.
I have only made a few mistakes so far that are due to inexperience; one of them was cutting the tubes about 2 inches too long that go from the radiator to the CPU, so the tube kind of loops around to get to the CPU. Another was not tightening the reservoir enough before I tipped the case sideways. Another big mistake would be that I should have picked another radiator. I will incorporate these changes in my next build, which probably won't be for a few years. It's really been fun messing around with the water cooling equipment though.
Also my pump tubing is a bit too long as well and I can't seem to get it to stick to where I want it, and I don't really want to drill a hole in the case, so I'll probably just zip tie it to the drive cage and hope it holds there. Maybe it's the inside surface of the HAF-X or maybe it's just the pump's sticky pad not sticking enough, it's hard to say. I was really happy that the pre-drilled holes for the radiator seemed to work great, but only connected in 4 spots.
I took some pictures but didn't have time to upload them this morning but should be able to tomorrow / tonight. I'm thinking about buying 2 x 200 mm fans from newegg; one to replace the existing non-LED top fan, another to fill in the spot where there is room for another 200mm fan. I'm not sure why Cooler Master didn't just include the second 200mm fan. For those buying the case I recommend ordering the second 200mm fan with it when you buy it to make things simple.
Noise-wise with the fans turned up to 1900 rpm it's audible (quiet compared with my old case but still audible), so looking over at the extreme systems forums I noticed that my radiator seems to perform best between 1400 and above, so I turned the fans to 1400 rpm and left them there. With the addition of the top 200 mm fan it should be enough push / pull action to compensate for the tight fins on the radiator.
The case is really wonderful in terms of routing wires. With a huge pack of zip ties I went to work and kept finding new ways to route the wires around. The case was huge but still a bit smaller than the corsair case. I don't know that I would be able to fit another radiator inside of the case, although I could probably hang a second radiator off of the back 140mm fan.
