I see that with RAM there's more than 1 number like DDDR3 1600 or 1333. What does they mean?
I found that out later like you did. That's why I'm going to go with the Cooler Master Hyper N520, it's cheaper and will probably get the same performance of the v10.
Do a little bit of searching of cpu coolers, I have read many threads that say the Cooler Master V10 is not a decent cooler. I just built a rig and I used a thermalright venemous x which has worked very well for me. My prior box had a cooler master cpu cooler in it and I had no issues i believe it was a cooler master Hyper z600R, but it was not the V10... if you dont plan to OC then most should work for you
