I've heard about kick starter ouyas having a few issues fan noise been a major one or loss of wifi-bluetooth etc.
My ouya was not new when I got it, I've replaced my fan because it was loud , apart from the looping boot up that's now fixed that's it,I'm happy with it
V2 obviously has the 16gb upgrade but is there any way to tell when your ouya was made or telling from a serial number what revision you have ,but they all look the same motherboard as well
