Pros: Good board after 2012 support has been fixed; it would be 5 eggs if the manuf. hadn't been caught with their pants down on a release so widely publicized. Using with 32GB of this ram: http://www.newegg.com/Product/Product.aspx?Item=N82E16820239116 and no problems. IPMI "fat" application is flaky, but the web daemon is better anyhow. Works well with an IBM 5014 (LSI 9260) controller. Onboard NIC performance is stellar, and having a dedicated IPMI port is a welcome chan...
Cons: Sometimes when I'm sleeping I think the motherboard is watching me. Is that weird?
Cons: No support for Windows Server 2012. As this is also sold in a 1U pre-assembled package, it would be good to label it as not supporting an operating system that is currently released. If you support the most recent CPUs it's utter nonsense that the most recent (available for 7mo now) OS would be as well
Cons: No support for Windows Server 2012 yet. After trying the Developers Preview, I opted to wait for RTM to hit the Microsoft VL site, and that copy does the same thing. BSOD after loading the files, and support has no desire to help since it's not supported. I'm sure it will take a BIOS update to fix, but who knows how far away that will be. I'm really disappointed about this, but guess I will use Server 2008 R2 instead.
Pros: Well designed hardware with a lot of features under the hood.
Cons: PCI-e cards cause all manner of uEFI malfunctions. Tried a video card that works in all other machines... tried a RAID card that works in all other machines... tried another video card in all other machines... Would post and then hang. The included video chipset is slow and clunky with VNC. Bought a PIKE to go with the board. The PIKE, at least with this board, is dreadfully slow. It's been initializing the RAID for a week now!
