Absolutely not reliable
1 first warranty return due to a mysterious failure (turned off then never turned on again after 1 month). 6 months later... too hot... turns off... but does not turn back on with a pink display. Finally after a few attempts to "reboot cold", it ends up "burning": smoke while it is 23deg in the room.
It is simply a poorly designed product. I've never had a problem with Zotac for example.
