AS Rock LGA1155 DDR3 SATA3 USB3.0 A GbE Mini-ITX Motherboard Z77E-ITX Review

I have a full-sized rig in my living room and wanted a smaller one for the bedroom. I needed a mini-PCIE slot on the motherboard for wifi and a Z77 chipset to take full advantage of the i7-3770K I got so cheap at MC. The highly rated Asus Deluxe mITX board was out of my price range so I was left to choose between Gigabyte and ASROCK. I had been at the same decision point for my full-sized rig and I first went with Gigabyte since I hadn't heard of ASROCK at that time. However the POST time was unacceptable so I ended up going with ASROCK for that computer. When I noticed a free RAM promotion at the Egg for the mITX ASROCK board, I jumped on it, though I would still have bought it at the asking price if I had to.

Pros:
1. mSATA slot on the underside. When I bought the board this was one of the main selling points because I could use the mSATA to hold a 256GB SSD as primary and free up space in the rest of the case for better airflow. However I didn't end up using it later because I was concerned about air-flow and heat down there. In hindsight, now that I have my case fully crammed, I think I might have been better served with a 64GB mSATA for intel RST (gives SSD-like performance without actually using the SSD as a drive) and just having another 2.5 HDD for data. It would have freed up a lot more space inside my tiny case. One minor caveat here is that the mSATA slot is SATA2 even if you have a SATA3 drive (unlike the newer ASROCK boards for Haswell that have SATA3 mSATA slots).
2. 8-pin CPU connector on the ASROCK versus 4-pin CPU connector on the Gigabyte. 4-pin is rated up to 150W and the 3770K can hit 160W at max load without overclocking (overclocked it can hit 250W). This is something I noticed post-purchase, so it was a good think I went with this board.
3. 4 USB3 ports on the ASROCK versus 2 USB3 ports on the Gigabyte board. It can support another 2 USB3 and 4 USB2 ports via headers.
4. It has an eSATA port which I will never use.
5. I needed the mini-PCIE slot for a wifi card and this was one of the few boards that has it. It already has a good quality Realtek wifi module, which is supposed to be better than the Broadcom module that most other motherboard manufacturers bundle with theirs. However it does not support 5GHz which I needed to fend off heavy interference at 2.4GHz in my highrise building. So I bought an Intel 6235 dual-band wifi + Bluetooth card Intel Network 6235AN.HMWWB Centrino WiFi Card Advanced-N 6235 Dual Band Bluetooth Retail and Antenna that support 5GHz Protronix 2dBi RP-SMA Antenna for Wireless PCI Card or Router. I thought the 2.4GHz antenna that was included with the board was too ugly to use anyway.
6. It comes with many extras like 2 SATA3 cables, an ugly but functional antenna, DVI-VGA adapter and a multimedia suite which I hear is pretty good but I've never tried. ASROCK also has a free overclocking utility that you can use in Windows for rather easy overclocking without messing around in the BIOS.
7. POSTS very quickly, even quicker than my Z77 Extreme4.

Cons:
1. I'm using a Thermalright AXP-100 cooler. The backplate make contact with the side of the mSATA slot causing some tension. The bracket for the cooler at the top makes contact with the capacitors that are lined up alongside the CPU. I was very fearful of causing damage while tightened everything down but luckily it turned out just fine. I could have used washers to add some clearance but I did not want to risk insufficient thermal contact with the CPU.
2. Antenna wires run all the way from the mini-PCIE card to the back of the antenna connectors on the back. Seems too fragile. They could have soldered these to the board closer to the mini-PCIE slot.
