I have just received the OEM version of a Gladiac MX I ordered. I am disappointed to see that the board is not the same board featured on the cover of the retail box. I chose this brand primarily for the low-profile board design but the OEM board I received is a regular full-height board. Another obvious difference is that this OEM board has a rather long heatsink as opposed to the regular square kind. Does anyone know about this OEM variant?
