Things I like about the XSPC Raystorm 750 RX360 kit are quite numerous. The reservoir and pump combo is not only attractive with the LED lighting and the aluminum cover plate, but the design with the pump inside made the loop simple to bleed and allowed me to get up and running much faster than other kits I've tested in the past. I am not such a fan of micro channels in a block, but there are no complaints about its performance or the appeal of the dual LEDs and aluminum cover plate to dress it all up. The thick radiator just screams extreme, and offers you plenty of opportunity to handle the motherboard blocks and multiple GPUs into the loop later on. I also like the fact that there were no parts missing and I was able to go from box to completely assembled, in very little time as well.
I do have a few things to complain about though, some personal, and some potentially detrimental. First off, what is with needing three Molex connectors and three fan headers? Why not power the CPU LEDs with a fan connection and simplify the wiring. Also what would be a tremendous help is that if these Molex connectors were a pass-through style so I don't have to have power leads running to each component.
The tubing used is very stiff and very sticky on the 1/2" barbs, and most times I wouldn't complain about this, but what ends up happening is when you reset the reservoir after filling it, the slight twist of the tubing will back the barb right out. They do have washers on all of the barbs, but even a quarter of a turn out and these barbs start to leak. Not only did it leak as I got finished bleeding it and inserting the reservoir all the way in, but when I carried it upstairs, any movement of the radiator would cause me to drip across my carpet. Compared to the others I have tested there is just an air of "budget" that overwhelms you as you build, test, and use this loop.
The Raystorm 750 RX360 kit does perform well as the results in the charts showed, and this is the most affordable kit that offers a triple radiator at this current time. Since I told you what to look out for, you could go to an auto parts store or the local hardware store and get some thicker washers at a cost of maybe a couple of dollars, I think then you can get enough bit against the surfaces to keep the barbs in place. I also thing using tubing that isn't so rigid may also aid in not twisting them in the first place. If you really can't afford to step up to the Swiftech or the EK offerings, this Raystorm kit will get you by.
In my honest opinion, I would gladly pay the extra $50 to get a kit that is leak free out of the box, and also getting a more professionally designed kit in the process. XSPC is close, but overlooking the simplest things on something like a water cooling loop can be devastating, and I for one am going to pass on the kit. I would however buy the block and the radiator as standalone pieces.
