Finding placement of the 250mm cooling fan in left side panel. We've positioned the fan 4" from the rear edge and 7" from the bottom edge of the panel.
Trace the outline fan with pencil onto the panel after applying 3M brand Green masking tape.
The masking tape also prevents scratches while cutting the fan hole.

Using 1/4" size drill bit to drill holes for fan silencing grommets.
Before we can using Jigsaw to cut the 250mm fan hole, we first make an incision for the Jigsaw blade with Rotary tool using 1.5" cutting wheel for dremel
We're using this styrofoam cushion to prop the panel so we have clearance below for using the Jigsaw.
Cutting 250mm fan hole with Jigsaw (use 18 TPI cutting blade)
A sheet of Honeycomb Modders Mesh will provide excellent ventilation
Cut down to 10" x 10" panel to serve as a grill for 250mm fan.
Let's paint the Modders Mesh Black to match our color scheme. First scuff the surface of the mesh with medium grit sandpaper to promote adhesion for the "self etching" primer base coat
After applying SEM brand "self etching" primer, we apply 3 coast of Plasti-kote Black enamel paint
4x Fan silencing grommets ready for installation
fyi: You can use a micro flat head screw driver to help gently pry the grommet into 1/4" hole
Finishing the edge of the 250mm fan hole with U-channel molding cut to 27.5" length
Our 250mm fan hole is finished and ready for installation of the fan!
You can mount the 250mm fan as your system "Exhaust" or "Intake" cooling fan, depending on individual hardware cooling needs.
We prefer to use #10 x 5/8" self tapping screws, these are Black Oxide
First lay down the Modders Mesh sheet (after the Black enamel paint has cured!
You will have to remove a small portion of the mesh around the mounting holes accommodate #10 x 5/8 self tapping fan screws
The 250mm fan mounts as an Exhaust. It pulls warm air out from inside your computer case.
Now you have a cooler running system with less fan noise than smaller fans!
