An apparatus includes a structure having a plurality of first sides and a second side detachably joined to the plurality of first sides. The plurality of first sides define a volume, wherein the second side has a closed position in which the second side is joined to the plurality of first sides and an open position in which the side is detached from the plurality of sides, the plurality of first sides comprising a first material having electromagnetic interference (EMI) shielding properties, the second side comprising a second material having EMI shielding properties. The apparatus also includes a movable chassis adapted to move between a first chassis position in which the chassis is entirely within the volume and a second chassis position in which at least a portion of the chassis is outside the volume, the chassis being adapted to hold an electronic device.
