Summary: I bought this board for a smaller footprint PC, Windows 7 Pro 64, and ALL the features that come with RAID. Installed 2x2Gb 1600 ram, no problems. Installed 2 HD in raid and 2 SSD in raid (yeah, crazy!). After some tweaking in the Raid, super fast boots, speedy Photoshop editing, great performance, nothing unusual like some of the previous comments. I'd recommend this to anyone using a socket 1156.
Summary: This motherboard works great and is easy to install. I paired this with an Intel i3-540 CPU. Windows XP runs great on this board. Just be sure to understand this is a micro-ATX board but should work in regular ATX cases (it did in mine). Unless you need a micro-ATX board I recommend a full ATX board. I haven't tried installing any expansion cards but all of the motherboard connectors where accessable and easy to hook-up.
