Hi,
need a backpack for my Helios 300 PH317-54

looking into the one below,but it says it is compatible only with PH317-51 and PH317-52

is there much of a difference between these and will it fit the PH317-54?
asking as it does not fit into one of my 17"laptop bags and difficult to fit it into another 17" laptop backpack I have.

Thanks,Tone
