I completed my first build yesterday and it is working great! I used the following components:
Gigabyte GA-Z77N-WIFI
Intel i7-3770K
Corsair Hydro H55 cooler
Corsair Vengeance 16GB DDR3 1600 MHz
BitFenix Prodigy Arctic White
SanDisk Extreme SSD 240GB
Seagate Barracuda 500GB 7200rpm
Corsair TX650 power supply
TP-Link Wireless N PCI-Express
Apple Magic Trackpad
Apple Wireless Keyboard
I have a nearly identical setup to alexvery and found his post very helpful:

It took a half day of fooling around with the install to get everything working properly. If I had read the description of MultiBeast more carefully I would have wasted less time---I didn't understand that it made the internal drive bootable--- but it was fun nevertheless.
I know many people have reported difficultly with bluetooth using this board. Mine is working well. It was very laggy initially, especially with the Magic Trackpad, but installing the supplied antennae helped a lot. Don't know if they are actually connected to the bluetooth part of the motherboard or are just helping with interference.
The cooler is a tight fit in the case. It interferes with the USB 3.0 connection to the front of the case, so I will either have to remount the cooler to the front or try to find some kind of low profile connector.
Geekbench score is 13988 (using the 64-bit setting).
