Another unhappy Falcon owner here. Rather than writing out a block of text I'll hit the important points quickly, both good and bad.

• Exceeds the original 27Mh rating, seems to average around 28Mh.
• Case looks nice.
• Packaging has inadequate shipping protection. Parts of the case were bent on mine and the screws that hold the boards on were loose. One of the fan cables was disconnected.
• Draws ~1115W consistently on a Raidmax 1000W 80 Plus Gold PSU. Coin diff has no impact on power use for me.
• Power connectors are not wired correctly and will short if you use the extra PCIe pins.
• Case fans blow air out the back (negative pressure) rather than sucking it in. This is opposite of the PSU and may cause cooling issues for the PSU.
• I won't list all the issues with the ZenController since they've been discussed elsewhere. Needless to say it feels like a prototype, not even alpha stage.
• Case is a few mm taller than 4U. This may make it unsuitable for rack mounting but I can't be sure as I haven't tested it yet.

To top it off sometime yesterday afternoon it stopped mining entirely. Sometimes it comes up as sick, sometimes it thinks it's hashing but doesn't output any results. Unfortunately I had to host it somewhere else due to power use and don't have physical access to it yet to diagnose. Hopefully I can get my hands on it today or tomorrow.
