its all about whether or not you want to take the risk. risk = learning. a friend of mine who is a pro now at building systems bent the pins when installing his CPU the first time around. The only issue is when there's an immense amount of re-wiring and internal connections to be done. fiddly motherboard pins and whatnot. luckily i have alot of boffins around to help me with this sort of stuff. but for the basics. its not all too fussy. I usually give myself a good 3 days and forced patience to build a system. lots of red bull and a stress ball xD
P.S most people who own the 920 overclock it straight out of the box from 2.66ghz to 3.7ghz @ 1.28v. Although it is recommended if doing so to use a more performance oriented CPU cooler, rather than the stock one that comes with it from intel. At these settings with a decent cooler it runs stable. This is my plan anyway. Just a heads up.
