* For LGA2011 you must buy CPU cooling solution separately, as none comes bundled. Additionally, Intel's own aftermarket solution, while very cheap, is rather loud and may appear inadequate for continous 100% load. Be sure to check if your computer case allows for appropriate aftermarket cooler or has enough mounting space for closed-loop watercooler.
* Be sure to check with the retailer if the board supports Ivy Bridge-E out of the box. While most do, there might be leftovers in stock that will require an update (using i7-3820/39xx) beforehand.
* I'd recommend against getting kit of 8. While arguably convenient, if one stick appears to be defective, retailers usually require sending the whole package and you'll be left with none during the exchange. Check warranty policies of your retailer to be sure. Or just to be safe, take 4 "kit of 2" packages.
Oh, and a less important note is that if no upgrades (additional GPUs mostly) will ever take place, that power supply might appear to be a little on the expensive side and also not very efficient. I suggest looking at something less powerful (500 to 600), but more efficient (80+ Gold). Might be the same price now, but you'll save some in the long run.
