The CECHH 40gb PS3 was an internal redesign of the CECHG, using a much smaller circuit board, a different hdd layout and new heat sink. This redesign also resulted in the shift of the rear connection ports from the right side to the left side of the console.
The feature set of the CECHH is identical to the CECHG model and is the second PS3 released with no backwards compatibility. Even though this model was an internal redesign it was actually released at the same time as the CECHG.
