A brace for a circuit board vertically mounted on a motherboard includes a first attachment member capable of attaching to an edge of the circuit board distal from the motherboard; a second attachment member capable of attaching to a side edge of the motherboard; and a rigid support connecting the first attachment member and the second attachment member. The rigid support is shaped such that the circuit board is held substantially perpendicular to the motherboard when the brace is attached. An interference minimization device for minimizing the interference of a circuit board vertically mounted on a motherboard includes an attachment member capable of attaching to the circuit board at an end distal from the motherboard; a mating wall that is substantially parallel to the circuit board and abuts the circuit board when the interference minimization device is attached to the circuit board; and a tapered wall that widens from the distal end of the circuit board towards the motherboard.
