For me the USB ports on the top of the case doesn't always work, which is weird. Sometimes it does, but more often than not it doesn't.
Also I'm running into another bizarre error, while I have Ethernet up and working after the first boot, after reboot it went offline completely. I followed an advice and remove Ethernet from the network manager in Settings, hoping it'd come back after reboot but alas, it doesn't. Anybody experienced anything similar?
Edit: figured it out, apparently if you boot using the USB (UniBeast) then the network would work due to the extra loaded kext in UniBeast. I finally got it to work by installing the latest Realtek ALC8111 kext (using MultiBeast is fine).
The audio however, still refuses to work, which is rather frustrating
