What is claimed is:1. A system, comprising:a server rack comprising:first and second opposing vertical supports defining an opening;a plurality of tabs on each of the first and second vertical supports within the opening; anda plurality of pairs of support surfaces, each pair of support surfaces comprising one support surface mounted on the first vertical support and another support surface mounted on the second vertical support, the pairs being equally spaced along a height of the supports; anda server mounted in the server rack opening, the server comprising:a chassis comprising first and second opposing sidewalls;protrusions extending from the first and second opposing sidewalls and configured to engage with respective tabs of the plurality of tabs when the server is installed in the server rack; andfor each sidewall, a flange coupled with the sidewall and extending laterally outward from the sidewall, the flanges on opposing sidewalls engaging a pair of support surfaces of the plurality of pairs of support surfaces, the flanges and the pair of support surfaces being arranged so that the flanges engage the pair of support surfaces during installation of the server to slidingly support the server when the server is installed in the server rack.2. The system of claim 1, wherein the tabs are removable from the respective first and second vertical supports and prevent the flanges from disengaging with the pair of support surfaces when the server is installed in the server rack.3. The system of claim 1, wherein the server includes respective flanges coupled with each sidewall, each of the flanges engaged with a respective support surface when the server is disposed in the server rack.4. The system of claim 1, wherein the server is a first server and the system further comprises a second server mounted in the server rack, the second server comprising:a chassis comprising first and second opposing sidewalls; andfor each sidewall, a flange coupled with the sidewall and extending laterally outward from the sidewall, the flanges on opposing sidewalls engaging a second pair of support surfaces on the server rack, the flanges and the second pair of support surfaces being arranged so that the flanges engage the second pair during installation of the server to slidingly support the second server when the second server is installed in the server rack.5. The system of claim 1, wherein the pairs of support surfaces are vertically spaced along the vertical supports at 0.5 U intervals.6. The system of claim 5, wherein pairs of support surfaces are vertically spaced along the height of the vertical supports at intervals of greater than 0.5 U.7. The system of claim 1, wherein the plurality of tabs extend into openings in the first and second vertical supports, each of the tabs defining an opening at one end for receiving at least a portion of a protrusion and wherein each of the tabs are moveable from a first opening along the height of the supports to a second opening along the height of the supports.8. A component rack, comprising:first and second opposing vertical supports;a plurality of tabs engaged with interior surfaces of each of the first and second vertical supports; anda plurality of pairs of opposing support surfaces mounted on the first and second vertical supports, the pairs being spaced along at least part of a height of the first and second vertical supports, the pairs of opposing support surfaces thereby forming slots for receiving electronic components at locations along the height of the component rack, a pair of opposing support surfaces of the plurality of pairs of opposing support surfaces configured to receive an electronic component comprising flange pairs and protrusions, wherein the flange pairs and the protrusions extend outward relative to respective sidewalls of the electronic component, and wherein the protrusions are configured to engage with respective tabs of the plurality of tabs when the electronic component is installed within a slot of the rack.9. The component rack of claim 8, wherein at least one of the pairs of opposing support surfaces comprises at least one of a C-shaped bracket or a U-shaped bracket.10. The component rack of claim 8, wherein one of the pairs of opposing support surfaces is a first shape and a different one of the pairs of opposing support surfaces is a second shape that is different than the first shape.11. The component rack of claim 8, wherein one of the pairs of opposing support surfaces spans only a portion of a distance from a front of the component rack to a rear of the component rack.12. The component rack of claim 8, wherein one of the pairs of opposing support surfaces further comprises a bearing for engaging with a flange.13. The component rack of claim 8, wherein the pairs of opposing support surfaces are spaced along only part of the height of the vertical supports.14. The component rack of claim 8, wherein the plurality of tabs are engaged with the first and second vertical supports in a plurality of tab pairs, each tab pair comprising a first tab engaged with the first vertical support and a second tab engaged with the second vertical support.15. The electronic component of claim 14, wherein at least one of the plurality of tab pairs are removable from a first engagement position and positionable at a second engagement position for engagement with the first and second vertical supports.16. An electronic component, comprising:a chassis with first and second opposing sidewalls;protrusions extending from the first and second opposing sidewalls configured to engage with respective tabs of a plurality of tabs mounted on opposing sides of a component rack when the electronic component is installed in the component rack; anda first flange extending outward relative to the first sidewall and a second flange extending outward relative to the second sidewall, the first and second flanges configured to engage with respective support surfaces mounted on opposing sides of the component rack to slidingly support the electronic component when the electronic component is installed in a slot of the component rack.17. The electronic component of claim 16, further comprising a lid spanning the first and second sidewalls of the chassis, a side of the lid contacting at least the first or the second sidewall when the electronic component is installed in the slot of the component rack.18. The electronic component of claim 17, wherein a portion of the first and second sidewall flares outward allowing the lid to engage with and sit below a height of the first and second sidewalls.19. The electronic component of claim 16, wherein the first and second flanges have a T-shape.20. The electronic component of claim 16, wherein the first and second flanges extend at least a portion of a distance from a front of the electronic component to a back of the electronic component.
