How to Build a Computer Cabinet With Proper Ventilation

by Martin Storbeck

If you have a media server or other hardware that you want to have out of your sight, don't just stuff it into a cabinet. Add some proper ventilation to it!


  • Some LEGO
  • 1 Notebook cooling pad
  • 1 Fan with usb connector
  • 1 Ventilation slot
  • 2 Hinges
  • 1 Wooden cabinet door
  • Your hardware
  • Instructions

    Step 1

    First: set up your devices in a cabinet

    Step 2

    Set up your computer in the cabinet. Wire everything.

    Step 3

    Raise HDDs using LEGO to have a better airflow

    Step 4

    You can add heat sinks to small metal cases. These will enlarge the surface of the case and enhance cooling. As you can see, I also put a notebook cooling pad under my Mac Mini.

    Step 5

    Second: Modify the door (you can also modify the cabinet, but doors are easier to replace)

    Step 6

    For the door you'll need to saw out holes for the fan and the ventilation slot

    Step 7

    Put a dust filter over the fan hole and put the ventilation slots in

    Step 8

    Add hinges so the door can be opened later

    Step 9

    Make sure that the fan blows air into the cabinet, not out

    Step 10

    Screw the fan to the door

    Step 11

    Screw the door to the cabinet

    Step 12

    The fan will suck in cold air, warm air can exit through the ventilation slot.

    Step 13

    Through the vent you can also see your HDD status if you place them right. On my Lacie, blue is good, red is bad, so everything is okay

    Step 14

    And: You're done
