  • Remove any external cables from the back and front of the case.
  • Open the case and use the screwdriver to remove CD/DVD, SSDs, HDDs, and any cables attaching them.
  • Look for any expansion cards attached to the case and remove them and the cable that powers your motherboard.
  • Carefully remove the motherboard using the necessary tools.
  • Remove the screws connecting the power supply from outside and inside and carefully remove the supply from the case.
  • Find the Velcro, stickers, and seals inside and outside the computer case. Ensure to use sandpaper where necessary to create an even surface for applying paint.

Step 1: Shut Down PC

Be sure you’ve turned off your computer correctly. Unplug the wall outlet and remove all cords, including the power cord, LAN, and all extra wires or cables connected to the case before proceeding with the process.

Step 2: Painting Location

A work area should be ventilated, allowing you to easily breathe while working with toxic paints or chemicals. Make sure you allow enough air and sunlight to come in, so the paint dries fast, along with supplying your body with healthy amounts of oxygen as well.

Step 3: Dismantle the Components

Locate the various pieces of your computer case and then carefully remove them. Put all of these components in a container that’s safe and dry so as not to rust or get damaged during painting, but keep them close by so you can put them back on when everything else has dried.

Step 4: Prepare the Surface

Be sure to clean the edges of the case where dust has collected. You could even go so far as to wipe down the internal components with a cloth and make sure that you have taken off the stick-on labels and factory plaques.

Step 5: Remove Old Paint

Removing the external paint from your product casing can get tricky. Be sure to wear the appropriate protective gear not to cause damage to yourself. I recommend sanding down the case with 220-grit sandpaper.

Make sure you get rid of all the existing paint on your project’s outer surface, as this will create a strong base for you to work with when it comes time to apply new paints. Smooth down the edges that still have remnants of paint by sanding them down. Be sure to use only one direction when sanding such that an excellent finish is possible

Step 6: Clean the Surface

Once you have done with the sandpaper and smoothed the edges, clean and remove the debris and particles from the PC case surface, Take a clean cotton rag and pour denatured alcohol into it in a sufficient amount.

Ensure to wipe the material and the sanded surface carefully. Once you have cleaned the surface with and removed all the debris, let it try for some time before proceeding with the next step.

Step 7: Apply First Layer

Before painting PC case with brush, apply a thin layer of paint carefully on the surface. Keep the angle and paint level uniform to paint perfectly. There is little involvement of the skill at this point, as achieving the perfect painting strike is impossible without a steady hand.

Don’t leave edges and corners unattended, as these areas need the most attention. Once done with the first coat, let it dry for some time. You can check the paint label and read about the drying time to be more accurate.

Step 8: Mastering the Art

Apply the primer using a brush and an even coating of paint. Let the paint dry for two hours, then apply paint again and let it dry for one hour before reassembling your computer. Some paints may require a primer coat before applying a topcoat, so you should check with your local supplier to see if this is the case.
