(In IBMs original heavy-gauge leaf blade case, the both 5-1/4 proficient-height drive bays overhang the front of the motherboard.

more(prenominal) precisely, the left wing bay overhangs the motherboard, while the right bay is subdivided into cardinal half-height bays and additionally extends down toward the bottom of the chassis, allowing a second gear full-height fixed record to be installed below a hit half-height drive.) The power connectors for AT motherboards are deuce nearly same 6-pin plugs and sockets. As intentional by IBM, the connectors are mechanically key out so that separately depose only be inserted in its correct position, but some(prenominal) clone manufacturers cut cost and used unkeyed (interchangeable) connectors. Unfortunately, the two power connectors it requires are not easily distinguishable, leading many people to damage their boards when they were improperly connected; when plugged in, the two black wires on each connector essential be adjacent to each other, do a track of 4 consecutive black wires (out...If you hope to get a full essay, order it on our website: Ordercustompaper.com
