What’s a Mechanical Keyboard Case?

Let’s start simple.
A mechanical keyboard case is the outer shell that hugs your keyboard’s insides: switches, plate, PCB (the circuit board), and all. Think of it as the body of your keyboard.
Here’s what the case affects:
- Sound: Some materials make your switches sound like a deep “thock,” others a sharp “clack.”
- Feel: Heavier cases keep your keyboard steady as a rock, while lighter ones feel easygoing.
- Looks: From shiny metal to glowing plastic, the case is your keyboard’s fashion statement.
- Durability: Tough materials shrug off bumps, while others need a bit of babying.
Picking a case material is a big choice!

How Case Materials Affect Typing

So, how do keyboard case materials change the way you type, game, or code?
These materials aren’t just eye candy. They affect sound, feel, and aesthetics in big ways.
Let’s break it down so you know exactly what you’re getting.
Sound
Your mechanical keyboard case is like a sound engineer for your switches:
- Plastic: Tends to sound hollow or high-pitched, especially in thinner cases.
- Aluminum: Delivers a sharp, crisp “clack” that’s clean and precise.
- Copper: Produces a deep, resonant “thock” that’s all the rage.
- Brass and Steel: Lean toward low, thocky tones for a rich, mellow sound.
- Acrylic: Sounds plasticky but softens with thicker or layered designs.
- Wood: Gives a warm, muted tone, like typing on a solid wooden desk.
Denser materials like copper or brass amplify low-frequency sounds, while lighter ones like plastic keep things bright.
Feel
The material’s weight and rigidity affect how your keyboard feels under your fingers:
- Heavy Materials (Copper, Brass, Steel, Aluminum): These make your keyboard feel like a tank, staying put no matter how hard you type.
- Lighter Materials (Plastic, Acrylic): Less weight means a softer, less anchored feel.
- Wood: Sits in the middle. It’s weighty enough for stability but with a smooth, organic touch.
Want a keyboard that doesn’t budge? Go for a heavy metal case.
Prefer something that feels airy? Plastic or acrylic.

Steel/Brass:
- Polish with a metal cleaner for that mirror shine.

- Decide if you love the aged look or want to keep it glossy.
Copper:
- Gently clean with a soft cloth to protect the anti-oxidation coating.
- Embrace the patina for a custom look or polish it off with copper cleaner.
