Summary: I bought this product with high hopes. I purchased from the Rover Mall through Amazon here. I received it and noticed that the seller's sticker was placed over top of the ASUS sticker where the serial number was. I didn't think much about it until I had to get technical support. It turns out the OEM sticker was cut off the box and covered up with the seller's sticker hiding the fact it was cut off.
Unless you're ready to search for Thunderbolt drivers, don't bother.

Summary: I bought the ASUS Z87-Deluxe/Quad for 2 reasons. I wanted a motherboard that supported more than six SATA drives (not including eSATA and DVD drives). I also wanted to tryout Thunderbolt 2.0 connectivity. I already had my external SSD a Seagate STAE133 External Thunderbolt sled. All was not well in paradise! The first thing I noticed when I installed Windows was that it did not run as fast on it as it appeared to on my ASRock Z77 Pro4-M, Ivy Bridge board.
Summary: I purchased this board for a 4770k build. 32GB of Patriot CAS 10 1866 ram, H60 water cooler, etc.. Completed the build and the system freezes momentarily once every 4-8 hours of use. Spent a month and a half reinstalling windows with various drivers, swapping out PSU, graphics card, ram and even got a new hard drive.. Use it a day and it freezes. Countless trips to Frys.. So I call support, which is spotty, sometimes very helpful, sometimes whoa its bad.
Summary: Not for Server O/S. Intel does not support or provide drivers for the on-board network card for server operating systems so I had to fit a PCIe card. What is the point of having two on-board network cards if you can not use them with Windows server? This board has ten SATA connectors. Who in their right mind would fit 10 hard drives to a client PC? This would be great for home / small business server duties if they would let it.
