Air baffle with integrated tool-less expansion card attachment

A computer system comprising:

• a circuit board disposed within a chassis;
• an air baffle with an integrated expansion card attachment disposed within the chassis;
• an expansion card having a handle attached thereto;
• wherein the air baffle comprises:
• a first wall comprising a first guide and a second guide projecting from a side surface of the first wall, wherein the first guide and the second guide form a transverse space therebetween;
• and
• a second wall parallel to the first wall disposed a distance from the first wall approximately equal to a width of the expansion card, wherein the second wall comprises a snap retainer having a projected portion thereof,
• wherein the transverse space formed between the first and second guides of the first wall has a size approximately equal to a thickness of the expansion card such that a first end of the expansion card is firmly held by the first guide and the second guide when the expansion card is inserted into the transverse space,
• wherein the projected portion inserts between the handle attached to the expansion card and the expansion card in order to hold the expansion card in place, and
• wherein the expansion card is held apart from and parallel to a circuit board of a computer such that an air channel is created between the first wall and the second wall for air to pass across the circuit board of the computer and the expansion card.
