Pros: All intel chips, runs esxi 5.5, 8 cores, support 32+ GB ram. IPMI and IP KVM with virtual media support.

Cons: If anything, just a bit slow, but hey... it's Atom.

Overall Review: This thing is a great replacement to my 2012 Mac Mini ESXi cluster. I'm using this for a home lab for Cisco UC. I bought two of these. I'm running esxi 5.5u1, 32GB Kingston ECC RAM. It's not the speediest of servers, but for what it offers in the form factor it's a great bang for the buck. I'm booting esxi from usb and can get 4-6 heavily used VMs running with little issue. The integrated IPMI and KVM support is top notch and what I expect from supermicro.

Pros: Short and sturdy. Just what I was looking for. The 4X internal 2.5" drive bay is great. The 1.5 U is no issue as I don't have to worry about finding a 1U panel to match my motherboard. Normal one works fine.

Cons: - No USB3 support. - Not able to flush mount under another device due to SFX power supply vents.

Overall Review: Using a silverstone SFX ST30SF powersupply. This works great as it's vents match up with the top vents in the case and still allow plenty of room for internal 2.5" drive bays. I installed the ASROCK extended ITX motherboard and as such had to make some very mnor modifications to remove the internal 3.5" drive bay and riser holder. No complaints.

Pros: Everything and more on this board. This will spoil me.

Cons: None so far.

Overall Review: Extended ITX was not an issue and knew what i was getting into before I bought. I used a ARK IPC-1.5U1525 case with minor modifications to remove one of the drive holders and the screw posts. This was fine for me as it also had a a 4x 2.5" drive bays Im using instead. I installed a retail i5 CPU that was listed on the ASROCK compatibility matrix and non-ecc ram.
