Pros: - Selected memory was automatically detected for dual-channel configuration 24h of memtest and 24h of mprime with no errors. - Supports 5 fans. Only CPU_FAN1 and CHA_FAN1 are 4-pin. CPU_FAN2 can be used to drive a case fan. - 3 dual-row USB connectors on MB: 1x 3.0, 2x 2.0 - HDMI + optical out works great for home theater setup - MB is 9.6"W x 8.5"D. Great for compact build (but see cooler issue below). - All motherboard devices operate correctly under Ubuntu 12.04 using Sandy Bridge CPU (probably also OK with Ivy Bridge, but have not yet tried this combo).

Cons: - Only 2 DIMM sockets, which wasn't really a con for this build - CPU coolers probably need to be < 140 mm wide for clearance with RAM, unless the cooler has enough height to clear the RAM. I found no ultra quiet low profile cooler for this build (the Arctic f11lp does not fit). The stock G530 cooler is not loud, but it's by far the noisiest component in the build and needs to be replaced due to the noise. - Heat sink on the south bridge seems a little weak for silent builds which typically have lower airflow. Highest chipset temp so far is 43.8C. - Don't buy the add-on ASROCK remote, which works with the onboard Nuvoton IR device. Low range and too many missed key presses.

Overall Review: The build: Silverstone ML03 HTPC case 300W SFX PS w/ATX adapter plate - watch out for clearance between PS and DVD in this case ASROCK H77M Intel G530 w/stock cooler (not loud, but too noisy for a silent build) 2x 4GB G-Skill F3-12800CL9D-8GBSR2 Sony OptiArc 8x SATA DVD 2x 1GB WD Scorpio Blue 2.5" HD 4x Noctua NF-R8 case fans w/adapter for all tach driven (2 may be enough) Xubuntu (Ubuntu + XFCE) 12.04 GMYLE VRC-1100 MCE IR remote with receiver OrientEX mini bluetooth handheld keyboard

Pros: Since I didn't have to pull this CPU cooler out of its clear packaging to judge the (mis-)fit in my build, I cannot comment on its function.

Cons: This cooler DOES NOT FIT on an ASROCK H77M micro ATX motherboard. The heat pipe ends span out into the area occupied by the closest memory DIMM. Maybe ultra low profile memory would allow a fit, but see below. While others have pointed out that mini-ITX boards can be a problem, there is at least one mATX board that also cannot use this cooler.

Overall Review: On the box, there is a reference to a "Height Restriction Drawing" available at Arctic's product page for this cooler, very near the bottom. I missed this in my purchase review. You can get there from the newegg page for this product. The relevant width of the cooler is 115mm. Perhaps ultra low profile memory would be able to fit under the heat pipe ends. The drawing indicates there is 29.4mm of room below them, measured from the surface of the motherboard (so don't forget to account for the stack height of the DIMM socket itself).
