Do-it-yourself guide to installing PC cooling fan and grill to top panel.

Measuring Square or Ruler.

Small Flat head screw driver.

Phillips screw driver.

120mm wire fan grill.

Center Punch.

Paint Pen or Marker.

Drill press (or Hand Power Drill)

Arbor for attaching 4.5" Hole Saw Attachment to Drill Press or Hand Power drill

4.5" Bi-Metal hole saw attachment.

Two Large C-clamps (if you're using Drill press.

Block of wood, to fit under the top panel.

Hand punch as shown here for making the screw mounting holes, or you can use a power drill.

If you don't have access to Drill press, you can use Hand Power Drill. Minimum volts for Cordless Power Drill is 18V, but 24v would be ideal for cutting into PC cases.

We're using Lian Li PC7-plus mid tower case for this tutorial.

Using Measuring Square to determine center location of the 120mm Wire PC fan grill.

Draw outline around the 120mm PC Wire fan Grill.

Now you have the exact location outlined for the Hole Saw guide bit.

Unscrew and remove the top panel.

Place the top panel on top of wood block, before using the hole saw.

I've placed pieces of acrylic material under the C-clamps, to prevent the panel from getting scratched or damaged. You can use scraps of thin wood or thick cardboard. *Tip: Apply Cutting Oil or WD40 to the edges of the Hole saw, to help prevent heat build up as it cuts the aluminum.

Next step is making the fan mounting holes

You will need to drill the fan mounting holes. I prefer using 1/4" size drill bit.

Use Round side hand file to debur the edges of the opening

You can use sandpaper as alternative to hand file.

Peel off tape and inspect work. You may want to use Medium grit sandpaper to give the edges a once over...

Stand back and admire your work!
