The cabinet can include multiple equipment bays within an interior space. The cooling sub-system can include one or more fans and/or ducts extending upwardly from a base of the cabinet between the equipment bays. The duct can include one or more vents configured to direct the cold air into the interior space, which can include toward specific portions of the interior space, such as the first and/or second equipment bays. ## Claims ### Claim 1 A cooling system, comprising: a computer equipment cabinet, the cabinet comprising a plinth, a first side wall extending upwardly from the plinth, a second side wall extending upwardly from the plinth opposite the first side wall, a rear wall extending upwardly from the plinth between the first and second side walls, a front wall extending upwardly from the plinth between the first and second side walls and opposite the rear wall, and an interior space; a first equipment bay within the interior space above the plinth; a second equipment bay within the interior space above the plinth; a first fan extending upwardly from the plinth between the equipment bays, the first fan configured to blow cold air from the plinth into the interior space; and a first duct extending upwardly from the first fan into the interior space between the equipment bays. ### Claim 2 (depends on 1) The system of claim 1, wherein the first duct includes a first vent configured to direct the cold air toward the first equipment bay. ### Claim 3 (depends on 2) The system of claim 2, wherein the first duct includes a second vent configured to direct the cold air toward the second equipment bay. ### Claim 4 (depends on 2) The system of claim 2, wherein the first duct includes a second vent configured to evenly distribute the cold around the interior space. ### Claim 5 (depends on 1) The system of claim 1, wherein the first duct is configured to direct the cold air toward the first equipment bay and further comprising a second fan extending upwardly from the plinth between the equipment bays, the second fan configured to blow cold air from the plinth into the interior space; and a second duct extending upwardly from the second fan into the interior space between the equipment bays and configured to direct the cold air toward the second equipment bay. ### Claim 6 (depends on 5) The system of claim 5, further comprising a third fan extending upwardly from the plinth between the equipment bays, the third fan configured to blow cold air from the plinth into the interior space; and a third duct extending upwardly from the third fan into the interior space between the equipment bays and configured to evenly distribute the cold air around the interior space. ### Claim 7 (depends on 1) The system of claim 1, wherein the first duct is a flexible duct configured to be adjustable in height and orientation. ### Claim 8 (depends on 1) The system of claim 1, further comprising a filter secured to the plinth adjacent to the first fan. ### Claim 9 (depends on 8) The system of claim 8, wherein the filter is disposed within the plinth adjacent to the first fan. ### Claim 10 (depends on 8) The system of claim 8, wherein the filter is disposed between the plinth and the first fan. ### Claim 11 (depends on 1) The system of claim 1, further comprising a filter secured to the plinth within a flow path of the cold air upstream of the first fan. ### Claim 12 (depends on 11) The system of claim 11, further comprising a second duct within the plinth between the first fan and the filter. ### Claim 13 (depends on 1) The system of claim 1, further comprising a discharge vent through the plinth configured to receive warm air from the interior space and transmit the warm air into the plinth. ### Claim 14 (depends on 1) The system of claim 1, further comprising a second duct extending upwardly from the plinth into the interior space between the equipment bays; and a second fan extending from the second duct, the second fan configured to blow cold air from the second duct into the interior space. ### Claim 15 A cooling system, comprising: a computer equipment cabinet, the cabinet comprising a plinth, a first side wall extending upwardly from the plinth, a second side wall extending upwardly from the plinth opposite the first side wall a rear wall extending upwardly from the plinth between the first and second side walls, a front wall extending upwardly from the plinth between the first and second side walls and opposite the rear wall, and in interior space; a first equipment bay within the interior space above the plinth; a second equipment bay within the interior space above the plinth; a first fan extending upwardly from the plinth between the equipment bays, the first fan configured to blow cold air from the plinth into the interior space; a first duct extending upwardly from the first fan into the interior space between the equipment bays, wherein the first duct includes a first vent configured to direct the cold air toward the first equipment bay; a second fan extending upwardly from the plinth between the equipment bays, the second fan configured to blow cold air from the plinth into the interior space; a second duct extending upwardly from the second fan into the interior space between the equipment bays, wherein the second duct includes a second vent configured to direct the cold air toward the second equipment bay; a third fan extending upwardly from the plinth between the equipment bays, the third fan configured to blow cold air from the plinth into the interior space; a third duct extending upwardly from the third fan into the interior space between the equipment bays, wherein the third duct includes a third vent configured to evenly distribute the cold air around the interior space; a fourth fan extending upwardly from the plinth between the equipment bays, the fourth fan configured to blow cold air from the plinth into the interior space; a fourth duct extending upwardly from the fourth fan into the interior space between the equipment bays, the fourth duct configured to be adjustable in height and orientation; a filter secured to the plinth within a flow path of the cold air upstream of the fans; a fifth duct within the plinth between the filter and the fans; and a discharge vent through the plinth configured to receive warm air from the interior space and transmit the warm air into the plinth. ### Claim 16 A cooling system, comprising: a computer equipment cabinet, the cabinet comprising a plinth, a first side wall extending upwardly from the plinth, a second side wall extending upwardly from the plinth opposite the first side wall, a rear wall extending upwardly from the plinth between the first and second side walls, a front wall extending upwardly from the plinth between the first and second side walls and opposite the rear wall, and an interior space; an equipment bay within the interior space above the plinth; a first fan adjacent to the equipment bay, between the walls, the first fan configured to blow cold air from the plinth into the interior space;
