I claim: 1. A computer system comprising: a plurality of computer modules; a computer cabinet holding the plurality of computer modules, the computer cabinet including an air inlet and an air outlet; and a multi-stage air mover carried by the computer cabinet, wherein the multi-stage air mover is configured to move a flow of cooling air from the air inlet, past the plurality of computer modules, and out the computer cabinet via the air outlet, wherein the multi-stage air mover includes first and second rotating blade sets, and wherein the multi-stage air mover further includes a stationary portion carrying a third blade set positioned in an annular arrangement about the axis of rotation, and wherein the third blade set is further positioned at least partially between the first and second blade sets. 2. The computer system of claim 1 wherein each of the first and second rotating blade sets includes a plurality of forward curved blades. 3. The computer system of claim 1 wherein each of the first and second rotating blade sets is positioned in an annular arrangement about an axis of rotation, and wherein the first and second rotating blade sets are at least approximately aligned in a radial direction extending outwardly from the longitudinal axis of rotation. 4. The computer system of claim 1, wherein the computer system further comprises a distributing member positioned proximate to the multi-stage air mover and configured to influence the flow of cooling air from the multi-stage air mover. 5. The computer system of claim 1, wherein the multi-stage air mover is a first multi-stage air mover having a first outlet, and wherein the computer system further comprises: a second multi-stage air mover having a second outlet; a mounting plate including first and second openings, wherein the first multi-stage air mover is attached to the mounting plate with the first outlet in fluid communication with the first opening, and wherein the second multi-stage air mover is attached to the mounting plate with the second outlet in fluid communication with the second opening; and a motor operatively coupled to the first and second multi-stage air movers to drive air through the computer cabinet via the first and second openings in the mounting plate. 6. A computer system comprising: a computer cabinet holding at least one computer module; and an air mover positioned inside the computer cabinet, wherein the air mover includes a plurality of radially positioned rotating blade sets configured to move a flow of cooling air through the computer cabinet and past the at least one computer module, wherein the air mover further includes a stationary blade set positioned at least partially between two adjacent rotating blade sets. 7. The computer system of claim 6 wherein each of the rotating blade sets is positioned in an annular arrangement about an axis of rotation, and wherein the rotating blade sets are at least approximately aligned in a radial direction extending outwardly from the longitudinal axis of rotation. 8. The computer system of claim 6 wherein the stationary blade set and the rotating blade sets are at least approximately aligned in a radial direction extending outwardly from the longitudinal axis of rotation. 9. A centrifugal air mover comprising: a first rotating blade set positioned in an annular arrangement about an axis of rotation; at least a second rotating blade set positioned in a generally annular arrangement about the axis of rotation, wherein the first and second rotating blade sets are at least approximately aligned in a radial direction extending outwardly from the axis of rotation; and a stationary blade set positioned at least partially between the first and second rotating blade sets. 10. The air mover of claim 9 wherein the first and second rotating blade sets and the stationary blade set are at least approximately aligned in a radial direction extending outwardly from the longitudinal axis of rotation. 11. The air mover of claim 9 wherein each of the first and second rotating blade sets includes a plurality of blades, and wherein each of the blades is longitudinally aligned with the axis of rotation. 12. An air mover assembly for use with a computer cabinet, the air mover assembly comprising: a mounting plate having first and second openings; a first multi-stage air mover attached to the mounting plate, the first multi-stage air mover having a first outlet in fluid communication with the first opening; and a second multi-stage air mover attached to the mounting plate, the second multi-stage air mover having a second outlet in fluid communication with the second opening, wherein at least one of the first and second multi-stage air movers includes: a first rotating blade set positioned in an annular arrangement about an axis of rotation; a second rotating blade set positioned in an annular arrangement about the axis of rotation; and a stationary blade set positioned in an annular arrangement about the axis of rotation, and wherein the first stationary blade set is positioned at least partially between the first and second rotating blade sets. 13. The air mover assembly of claim 12 wherein the first and second blade sets are at least approximately aligned in a radial direction extending outwardly from the longitudinal axis of rotation. 14. The air mover assembly of claim 12 wherein the first and second rotating blade sets and the stationary blade set are at least approximately aligned in a radial direction extending outwardly from the axis of rotation. 15. The air mover assembly of claim 12 wherein the stationary blade set includes a plurality of straightening vanes. 16. A method for cooling a plurality of computer modules carried by a computer cabinet in a room, the computer cabinet including an air inlet and an air outlet, the method comprising: positioning a multi-stage air mover in the computer cabinet; and operating the multi-stage air mover to drive a flow of cooling air from the air inlet through the computer cabinet, past the computer modules, and into the room through the air outlet, wherein the multi-stage air mover includes first, second, and third blade sets at least approximately aligned in a radial direction extending outwardly from an axis of rotation, wherein operating the multi-stage air mover further comprises: compressing the flow of cooling air from the air inlet to a first pressure with the first blade set; at least partially radially directing the compressed cooling air from the first blade set to the third blade set with the second blade set; and further compressing the directed cooling air to a second pressure higher than the first pressure with the third blade set. 17. The method of claim 16 wherein positioning a multi-stage air mover includes mounting a multi-stage air mover toward a bottom portion of the computer cabinet. 18. A system for performing high-speed computations, the system comprising: means for holding at least one computer module; means for admitting a flow of cooling air from a room into the computer module holding means; a first compressing means for compressing the flow of cooling air to a first pressure; and a second compressing means for compressing the flow of cooling air from the first pressure to a second pressure higher than the first pressure, wherein the second compressing means are positioned in an annular arrangement around the first compressing means, wherein the system further comprises an air directing means for at least partially radially directing the flow of cooling air from the first compressing means to the second compressing means. 19.
