1. A line card comprising: a metal frame including: a front section, anda bottom section connected to the front section via an angled section, the angled section resulting in an opening between the line card and a second line card, when the line card is installed above the second line card in a rack
1. A line card comprising: a metal frame including: a front section, anda bottom section connected to the front section via an angled section, the angled section resulting in an opening between the line card and a second line card, when the line card is installed above the second line card in a rack, andthe opening allowing directed air to enter the rack from a front direction;a printed circuit board (PCB) attached to the metal frame; anda plurality of front panel connectors attached to the front section of the metal frame. 2. The line card of claim 1, where a width of the opening is substantially equal to a width of the line card. 3. The line card of claim 1, where the metal frame further includes: an extended top section connected to the front section, where the extended top section contacts a metal frame of a third line card, when the line card is installed below the third line card in the rack. 4. The line card of claim 3, where the extended top section includes a plurality of openings, and where the plurality of openings allow the directed air to enter the rack from the front direction. 5. The line card of claim 4, where the plurality of openings further prevent electromagnetic (EM) interference from passing through the extended top section. 6. The line card of claim 5, where a frequency of the EM interference is higher than a threshold, and where a size associated with the plurality of openings is based on a wavelength of the EM interference. 7. The line card of claim 4, where the extended top section further includes an increased density area, where the increased density area includes a higher density of openings than a density of openings of another area of the extended top section, andwhere the increased density area allows increased air flow to enter the rack at a location of the increased density area. 8. The line card of claim 7, where the increased density area is aligned with a heat generating component located on the PCB of the line card. 9. A rack comprising: a plurality of line cards mounted in the rack; anda plurality of openings located between adjacent ones of the plurality of line cards, a particular opening, of the plurality of openings, extending substantially a width of the rack and the particular opening being located between a first particular line card and a second particular line card of the plurality of line cards, the first particular line card being mounted immediately above the second particular line card,the plurality of openings allowing directed air to enter the rack from a front direction,a third particular line card of the plurality of line cards including an extended top section, the extended top section contacting a metal frame of a fourth particular line card of the plurality of line cards, when the third particular line card is installed below the fourth particular line card in the rack, andthe extended top section including a plurality of second openings, the plurality of second openings allowing the directed air to flow to the third particular line card. 10. The rack of claim 9, further comprising: a backplane located in a plane substantially parallel to the plurality of openings, the back plane including one or more openings that allow the directed air to exit the rack. 11. The rack of claim 10, where the backplane further includes one or more exhaust fans to facilitate the directed air to exit the rack. 12. The rack of claim 9, where the plurality of second openings further prevent electromagnetic (EM) interference from passing through the extended top section. 13. The rack of claim 9, where the extended top section includes an increased density area, where the increased density area includes a higher density of openings than a density of openings of other areas of the extended top section,where the increased density area allows increased air flow to enter the rack at a location of the increased density area, andwhere the increased density area is aligned with a heat generating component located on a printed circuit board of the third particular line card. 14. The rack of claim 10, where the backplane includes an exhaust fan to facilitate the directed air to exit the rack, and where the exhaust fan is aligned with the increased density area. 15. A method comprising: forming a front section of a metal frame for a first line card; andforming an angled section in the metal frame, the angled section connecting a bottom section of the metal frame to the front section,the angled section resulting in an opening between the first line card and a second line card, when the first line card is installed above the second line card in a rack, andthe opening allowing directed air to enter the rack from a front direction. 16. The method of claim 15, further comprising: forming an extended top section of the metal frame, connected to the front section, where the extended top section is connected to the front section and contacts a metal frame of a third line card, when the first line card is installed below the third line card in the rack. 17. The method of claim 16, further comprising: forming a plurality of openings in the extended top section of the metal frame, where, when the first line card is installed in the rack, the plurality of openings allow the directed air to flow to the first line card. 18. The method of claim 17, further comprising: forming an increased density area in the extended top section, where the increased density area includes a higher density of openings than a density of openings of another area of the extended top section, andwhere, when the line card is installed in the rack, the increased density area allows increased air flow to enter the rack at a location of the increased density area. 19. The method of claim 17, where the plurality of openings prevent electromagnetic (EM) interference from passing through the extended top section. 20. The method of claim 15, where a width of the opening is substantially equal to a width of the first line card.
