Preparation: Clean the case, remove stickers and sand the surface
Preparation is key to achieving a fantastic finish when painting your computer case. Here is a step-by-step guide to preparing your computer case for painting:
Clean the Case
Start by giving your computer case a thorough clean. Use warm water with a mild detergent, such as washing-up liquid, and a sponge. Rinse the case with water and allow it to dry naturally. This step will remove any dirt, grime, or fingerprints that may affect the paint finish.
Remove Stickers and Case Accessories
Make sure to remove any stickers, as well as case buttons, ports, and dust filters. Stickers may leave residue, so give the area an extra wipe with your detergent solution. These accessories can become clogged with paint and stop functioning, so it is important to take them off before painting.
Sand the Surface
Use sandpaper to sand the surface of the case. If there is old paint on the case, use low-grit sandpaper (200 or less) to remove it. Gradually increase the grit of the sandpaper until the case feels very smooth. If there are deep scratches or dents, fill them with putty and sand them down with 800-grit sandpaper. Don't forget to wear protective gloves and long clothes to protect your skin and prevent transferring oils from your fingers to the surface.

Dismantling: Unscrew or drill out rivets to take the case apart
To paint the inside of your computer case, you will first need to dismantle it. If your PC case is screwed together, it is easy to remove the screws. However, if it is riveted, you will need to drill out the rivets.
To drill out the rivets, start with a 3mm drill bit and increase the bit size gradually until you drill the rivet out of the case. The holes are usually 3mm, 4mm, or 5mm wide. You can also use an old flat-bladed screwdriver to shear the head of the rivet off. Align the screwdriver flush with the riveted surface and against the domed rivet head. One or two short, sharp blows to the back of the screwdriver will shear off the head of the rivet. Most of the time, both halves of the rivet will drop out, but occasionally, the 'bulged' part remains in the hole and can be pushed or pulled through.
Before painting, it is important to clean the case to remove any fingerprints, stickers, or grime that may affect the paint finish. Use warm water with a dash of washing-up detergent and a sponge, rinsing thoroughly afterward and allowing it to dry naturally. Remove any case buttons, ports, and dust filters, as these parts can become clogged with paint and stop functioning.
It is also recommended to fill and sand any deep scratches and dents, as they are unlikely to be solved by filling them with primer. Use 3M glazing putty and a spatula or old flexible plastic card to smooth the putty into the scratches, then use 800-grit sandpaper to finish.

Painting process: Use spray paint, primer and enamel
Yes, you can paint the inside of your computer case. Here is a step-by-step guide on how to do it using spray paint, primer, and enamel:
Preparation:
Before you start painting, there are a few things you need to do to prepare your workspace and the computer case:
- Choose a well-ventilated area or set up a plastic greenhouse to contain the spray paint and prevent insects from landing on surfaces. Ensure you are wearing protective gear, including gloves, long clothes, goggles, and a respirator face mask.
- Dismantle your computer case by removing screws or drilling out rivets. Take photos at each step so you know how to put it back together.
- Clean the case with a degreaser such as white spirit or ammonia, or use warm water with a dash of washing-up detergent and a sponge, rinsing and drying thoroughly afterward.
- Remove any case buttons, ports, and dust filters that can become clogged with paint and no longer function.
- Fill in any deep scratches or dents with 3M glazing putty and a spatula or old flexible plastic card. Sand the filled areas with 800-grit sandpaper to smooth them out.
- Sand the entire case with fine-grit sandpaper to create a smooth surface for the paint to adhere to. Start with the edges, then move to the larger surfaces, sanding in a circular motion.
- Wipe away any dust with a damp cloth, then use a tack cloth to remove any remaining dust particles.
Painting Process:
Once your computer case is prepared, you can start the painting process:
- Apply the primer using a paintbrush or roller, working in small sections and using even strokes to avoid drips or runs. Allow the primer to dry according to the manufacturer's instructions.
- Lightly sand the primed surface to smooth it out.
- Shake your spray paint can according to the manufacturer's instructions, then test spray on a piece of cardboard or scrap material to get a feel for the spray pattern and pressure.
- Start spraying slightly before you reach the case and continue spraying slightly after you pass over it, using overlapping strokes. It is better to apply several thin layers than one thick coat, which can drip or run.
- Allow the paint to dry completely before reassembling your computer case and powering it on.
Tips:
- Enamel spray paint is a great option for painting computer cases as it is durable, scratch-resistant, easy to apply, and quick-drying.
- Summer is the best time for spray painting as the paint dries faster, and you can work in a well-ventilated outdoor space without freezing temperatures.
- If you are painting the interior and exterior of your case, you will need about two cans of primer and color coat for each.
- Tape off all screw holes, especially the power supply, to ensure they are not painted and maintain proper electrical grounding.
- Always follow the manufacturer's instructions for use and safety when using spray paint and primer.

Safety: Avoid inhaling paint fumes and ensure proper ventilation
Painting the inside of your computer case can be done, but it is important to take the necessary safety precautions to avoid any potential health risks associated with inhaling paint fumes. While most paints are generally safe, exposure to paint fumes can cause irritation to the skin, eyes, and throat. Some paints contain volatile organic compounds (VOCs) that can be released into the air as gases and potentially cause both short-term and long-term health effects. Therefore, it is crucial to ensure proper ventilation when painting indoors.
To avoid inhaling paint fumes, it is recommended to select a paint with lower VOC levels or choose a paint that is VOC-free and odorless. You should always read the labels and follow the manufacturer's instructions for usage and safety precautions. When painting, make sure the area is well-ventilated by keeping windows and doors open to allow fresh air to circulate. Using fans can also help keep the air moving and encourage cross-ventilation. It is important to maintain ventilation for at least three days after painting to ensure that any remaining paint fumes are eliminated.
Taking breaks during the painting process is essential to remove yourself from the immediate environment and get some fresh air. It is also recommended to cover your skin and wear protective gear, such as goggles, and a respirator, to minimize direct contact with paint fumes and particles. If possible, isolate the painting area from the rest of your living space to prevent paint fumes from spreading to other rooms. This can be done by closing vents or using plastic sheeting to create a temporary barrier.
In addition to ventilation, proper preparation of the computer case before painting is crucial. Make sure to clean the case with a degreaser, such as white spirit or ammonia, and allow it to dry thoroughly before applying paint. If you are using spray paint, practice on a test piece first to get a feel for the spray pattern and technique. By following these safety guidelines, you can effectively avoid inhaling paint fumes and ensure a safer painting experience when painting the inside of your computer case.

Drying: Allow paint to dry thoroughly before reassembling
Painting your computer case is a great way to give your PC a unique look. However, it is important to be patient and allow the paint to dry thoroughly before reassembling your computer.
Spray paint typically dries to the touch within 15 minutes to an hour. However, it is important to note that the paint is not fully bonded until 24 hours have passed. Therefore, it is recommended to wait at least 30 minutes to an hour between coats and at least 24 hours before reassembling your computer.
The curing process, during which the paint continues to release fumes and bond to the surface, usually takes around 5-7 days for spray paint. Applying a clear coat before the paint has finished curing can cause the fumes to build up and crack the clear coat.
The drying time can be influenced by several factors. For example, painting during the summer or in a warm area can help accelerate the drying process, while winter temperatures can prolong it. Additionally, metal or aluminium surfaces tend to dry faster than plastic ones.
To ensure a smooth and even finish, it is important to maintain a steady and constant sweeping motion while spraying. Avoid stopping at dry edges, as this can result in shadow lines in the finish. Instead, always paint from a wet edge outward. Applying several light coats is preferable to a single thick coat, which can cause wrinkling.
