Pros: C226 Chipset gives you DVI, HDMI and DisplayPort out using your 12x5-series v3 Xeon with integrated graphics saving you badly needed PCIe lanes 16 lanes of PCIe 3.0 goodness another 4 lanes of PCIe 2.0 to fall back on Onboard NICs (Intel I210's...not bad) use 1 lane each... Up to 32GB of DDR3 with UDIMM ECC (unbuffered/unregistered) support (as long as you use a Xeon and not a 4th Gen Core i3/i5/i7 (Haswell) USB 3.0 ports on rear as well as a header on MB for additional lanes to front or back as you so choose VT-d support UEFI BIOS with overclocking support (fully tunable thanks to ASUS' superior engineering support)

Cons: As far as I can tell, no SR-IOV support as of BIOS release 1707 (1/16/2014)...Chipset, CPU, and Intel NIC (I350-T4) should all be playing together nicely as VT-x and VT-d support is present and enabled...but no SR-IOV support in BIOS (per MS Windows Server 2012 R2 diagnostics) as ACS for PCIe is not supported This is a BIG con for me...minus 2 stars ASUS - get your act together and add SR-IOV support BIOS!

Pros: Functional. Nice scratch-resistant finish

Cons: Horrible tolerances. Frame bends to accomodate 2.5" drives and bends further to fit in 5.25" drive bay. I cannot recommend this to anyone that is looking for a properly machined part.
