Suggestions for CPU Cooler and Cases

It's very, very rare to see a liquid cooler leak unexpectedly. I have the Corsair H75 and is very effective at cooling my CPU down. Air cooling is more reliable and can even defeat a liquid cooler in terms of cooling potential, but some can be very tall and wide, thus compatibility is an issue. A Noctual NH-U12S is an excellent air cooler. Easy to set up, built like a freaking panzer tank and cools incredibly well whilst being virtually silent, if you like the color of the fan that is.

Onto your case dilemma. You really don't need a full size case for your system. That motherboard will fit any mid tower case on the market. My recommendation, a Fractal Design Define S. Its a very silent case, has bags of watercooling potential and looks elegant. All being cheaper than all the cases you have on show. Looks don't make the case. I learned that the very hard way with my first build, which the case looked awesome, but the metal felt like it was gonna shear every time I screwed the panels in.

No, don't use the stock cooler on that nice of a board lol (it was designed for OCing)!
If I were you id personally buy these items below:

In my opinion i just love this case, it can fit up to 3 full size GPUs and still have 2 slots left open and is actually quite small! ( I just love this little shit <3 )

Thats about as much as you want to spend. Hope i helped!

The cases you selected are actually all decent and if you bought them, there really wouldn't be any issues. You don't NEED a Full Tower to house all this, but the extra room makes it easy for assembling and upgrading. The problem with says "Hey, buy this case" is that there is always aesthetic opinions. My opinions may differ from yours, but I'm going to try to give you cases that are of good quality and have a stable brand name (i.e. Corsair and NZXT).

http://bit.ly/1LfzdWg - Corsair 750D (Rather large, high quality materials, and good price.)
http://bit.ly/1c75wur - NZXT H440 (Decent size, REALLY sleek/clean look, high quality materials, "silent" case, comes in a variety of colors/flavors, and good price.) You'd have to buy an external optical drive if you need to install your OS.
http://amzn.to/1Ahbt3E - Corsair 780T (Fairly large, high quality, decent looking, lots of room to work with, tons of features, somewhat clean look, and an okay price.)

Those are some of my personal favorites and would actually purchase these if I had the money to. Granted, whatever case you choose, make sure you like it and won't have a problem staring at it a lot! We all know we like to marvel at our completed builds from time to time!

As for the CPU cooler, there really isn't much to say. It all depends on what type of cooling you want. No, water cooling is not dangerous. There is a very, very, very, VERY low change that anything will just bust and ruin everything. Nothing will go wrong if you properly install the cooler, which there are very detailed tutorials online on how to do so.

If you feel confident enough to go with water cooling then there's one that stands out among the crowd:

http://bit.ly/1rcNcSQ - Corsair H100i ($100, so make sure the case you buy is also around this much or lower. Great quality and reliable.)

There's a much more cost effective way to spend money on a CPU cooler and get great temperatures too!

http://bit.ly/19hF9uw - Hyper 212 EVO (This thing is less than $30 and will cool your CPU for life and still give good temperatures.)

People may say I'm a little Corsair biased and I could partially agree, but that's only because they provide very good quality products. But if I were you, I would personally go with a good quality case, such as the ones I listed above, and buy the Hyper 212 EVO.

Side Note: You will have to apply thermal paste to your processor before installing the Hyper 212 EVO.)

u should get fractal design define r4 its cheap and pretty big with plenty of space
