"Turn your Dead PC into an Aquarium"

Step 7 Air/Food Tube

We need to drill a hole in the top of the PC to insert an Air/Food tube. You can mark your hole by taking the tank lid and laying it on top of the PC. Using the same method that we used to mark the mounting hole for the bottom the the Aquarium lid, mark the center hold for the air/food line. I used a 11/8" in Bi/Metal hole saw to make the cut. Your tube needs to line up exactly with the hole you cut in your lid.

After you cut the hole in the top of the PC cut your 3/4" in PVC pipe down to 7 3/4" in to use as the Air/Food Tube

After paint cap it off with a 3/4 " in coupler and 1 1/4" in cap with a 3/4" in hole cut into it.
