Your keyboard case shapes the sound, feel, weight, durability, RGB look, and overall vibe of your build. Below is a quick, plain-English comparison of popular case materials and when to pick each.
Quick picks:
Deep, muted sound → Acrylic or Wood
Crisp, loud keystrokes → Aluminum or Brass
Unique aesthetics → Wood, Acrylic, Carbon Fiber
Budget-friendly → Plastic (ABS/PC/PBT)
Maximum rigidity & durability → Stainless Steel or Carbon Fiber
Best all-rounder → Aluminum
Key Specifications
Plastic (ABS / Polycarbonate / PBT)
- Sound: Hollow/“plasticky”; PC leans softer “thock.”
- Feel/Flex: More flex; comfy and forgiving.
- Weight: Light. Cost: Low. RGB: Excellent diffusion (esp. PC).
- Use: Beginner builds, RGB-heavy setups.
Aluminum
- Sound: Crisp, bright “clack.”
- Feel/Flex: Rigid, premium.
- Weight: Medium–heavy. Cost: Mid–high. RGB: Subtle.
- Use: Most common enthusiast choice; versatile.
Brass
- Sound: Deep, resonant; very “solid.”
- Feel/Flex: Ultra-rigid.
- Weight: Heavy. Cost: High. RGB: Minimal diffusion.
- Use: Luxury builds, weights/inlays.
Stainless Steel
- Sound: Loud, bright; can be pingy without dampening.
- Feel/Flex: Extremely stiff, durable.
- Weight: Very heavy. Cost: High. RGB: Minimal.
- Use: Niche, showcase durability/rigidity.
Acrylic
- Sound: Soft, muted; pleasant thock.
- Feel/Flex: Slight flex = gentle bounce.
- Weight: Light–medium. Cost: Low–mid. RGB: Great diffusion.
- Use: Layered cases, DIY kits, RGB shows.
Wood
- Sound: Warm, rounded.
- Feel/Flex: Firm but not harsh.
- Weight: Medium. Cost: Varies by craft/wood. RGB: Depends on design.
- Use: Unique/artisanal builds.
Carbon Fiber
- Sound: Bright, snappy.
- Feel/Flex: Zero flex; performance-oriented.
- Weight: Very light. Cost: High. RGB: Limited diffusion.
- Use: Travel boards, high-performance rigs.
Pros
Plastic: Affordable, forgiving, great RGB.
Aluminum: Balanced, premium feel, widely available.
Brass: Lux look/weight; deep, resonant acoustics.
Stainless: Maximum stiffness and durability.
Acrylic: Muted acoustics, RGB-friendly, approachable price.
Wood: Unique aesthetics, warm tone, one-of-a-kind grain.
Carbon Fiber: Ultra-light, rigid, “fast” feel.
Cons
Plastic: Can sound hollow without foam/dampening.
Aluminum: Can be sharp/bright if undampened.
Brass: Expensive, very heavy; fatiguing to move.
Stainless: Loud/bright; needs careful dampening; heavy.
Acrylic: Scratches easier; less impact-resistant than metals.
Wood: Quality varies by craft; sensitive to humidity.
Carbon Fiber: Costly; brighter sound; limited RGB diffusion.
Common Mistakes
- Choosing stainless/brass for portability—weight adds up fast.
- Expecting acrylic to be as durable as metal; it isn’t.
- Picking plastic and skipping foam/dampening, then blaming the case for hollowness.
- Assuming wood needs no care—humidity and finish matter.
- Ignoring that case material isn’t the only acoustic factor (plate, mount, foam, keycaps all matter).
- Buying for RGB diffusion but selecting metal cases that won’t showcase it.
Key Takeaways
Case material sets your build’s acoustic character, rigidity, weight, and look.
Aluminum is the safest all-round pick; acrylic/wood for warm/muted & RGB; brass/stainless for ultra-rigid statement builds; carbon fiber for light, snappy performance; plastic for budget/RGB and flexibility.
Plan dampening (foam, gaskets, tape mods) to fine-tune any material.
Match material to your priorities: sound goal, portability, RGB, budget, and maintenance.
