Pros: Perfect board for NAS or small vhost! Small, quiet, 8 cores, up to 64gb RAM, virtualization support, great performance/watt, quad Intel gig ethernet, crypto/compression accelerator (C2758 only), built-in IP KVM and other server-grade features! Supermicro support on top of Newegg service! Board is dead-silent and even when running full-bore on the bench with no air circulation it only hit 75C - it got hot, but never came close to the 90 degree C max temp. Installed in a Node 304 case with normal airflow and system load it rarely exceeds 36C and idles at 36 watts. Under full load it can reach ~40C and ~50 watts.

Cons: First board was bad.

Overall Review: First board was bad, but Newegg swapped the board without hassle. Used shoprunner so got free shipping. Supermicro would cross-ship a replacement if I'd needed the board immediately. The ATOM C2758 isn't as fast as new D-1540 low-power Xeon's, but is enormously cheaper and is still lower power. Newer Xeon's are on the way with 25W TDP but they're not out yet, and it's unknown what performance compromise was made to hit that low TDP rating. Very happy with this board.

Pros: Worked perfectly, fast, no defects.

Cons: None.

Overall Review: Server grade ("KF") ECC RAM for my Supermicro A1SRi-2758-F. Works perfectly, no complaints.

Pros: Great power supply, very efficient. Fan doesn't run if the supply isn't warm, and the supply rarely gets warm. Has enough connectors for small systems but for NAS need to add additional SATA power connectors. Dropped idle power consumption for my NAS from ~80W to ~52W.

Cons: Only 3 SATA power connectors and two 4pin MOLEX.

Pros: Compact case Decently quiet fans Built in fan controller Good layout Thumb screws everywhere Built in air filters

Cons: No power supply Fans don't support PWM Top cover isn't as easy to remove as some Filters can rattle Not enough activity indicator lights (LAN, overheat, etc.) Requires screwdriver and thumbscrews to remove drives

Overall Review: This is a decent relatively well made case with great layout. On sale, it's a decent buy. At full price, not so much.
