Top left has reg phone jacks. Remove or stay in circle? Do i remove the small wire wound copper coils? I am guessing these r periph. Is it periph if it is an I/O board from inside a comp instead of external device?

The thing in the red circle looks like a battery, remove it just in case. These boards seem to represent the entire category of high grade peripheral. The 2 on the upper left are on the bottom end and the other three are on the high side. Remove the bracket on the bottom board. Peripheral is just the name of the class, not the function of the board

Thank you. I just watched the vid on periph. Have some lcd tv boards I thought weren't worth much.
Edit Not a batt. Cap. I 4get that parts are marked.
