Decision 07 of 13

Case material

Weight, sound, price and that premium feel.

The case material drives heft, acoustics and cost. Dense materials like aluminium and brass make a board feel planted and premium and lower the pitch of the sound; plastics keep it light and cheap. The case material also interacts heavily with the mounting style and any foam to shape the final sound signature.

Metal (aluminium / brass)

CNC-machined aluminium is the enthusiast standard — heavy, rigid and premium, with a deeper sound. Brass weights are often added inside. The priciest option by some margin.

Polycarbonate

A semi-translucent plastic prized for a softer, deeper, "marbly" sound and a slightly bouncier typing feel. Great with RGB underglow, and friendlier on the wallet than metal.

Acrylic & plastic

Stacked acrylic layers are cheap, customisable and look fantastic with lighting. Moulded ABS plastic is the lightest and most affordable, common on entry kits.

Wood & FR4

Wood looks warm and unique but varies in acoustics. FR4 (the same material as PCBs) is a niche, lightweight choice with a distinctive sound, often used for plates and budget cases.

The options, compared

Every choice you'll see for this decision in the builder.

CNC aluminium
Premium

Machined from a solid billet. Substantial, beautifully finished, and the deepest, most refined sound. The most "gift-worthy" feel.

Pros
  • Premium heft & rigidity
  • Deep, refined acoustics
  • Anodised in many colours
Trade-offs
  • Most expensive
  • Heavy to travel with
Polycarbonate
Soft & deep

A favourite for its bouncy feel and mellow, marbly acoustics. Semi-translucent, so it glows beautifully with underglow.

Pros
  • Soft, deep sound
  • Bouncy, forgiving feel
  • Glows with RGB
Trade-offs
  • Less premium heft
  • Can flex if thin
Acrylic stack
Customisable

Sheets of acrylic stacked together. Affordable, endlessly customisable, and stunning with RGB shining through the edges.

Pros
  • Affordable & customisable
  • Spectacular with lighting
  • Easy to source
Trade-offs
  • Can scratch / show fingerprints
  • Less "solid" feel
Moulded plastic (ABS)
Light & cheap

The standard for mass-market and entry kits. Light, cheap and perfectly serviceable, if less luxurious.

Pros
  • Cheapest option
  • Very light / portable
  • Widely available
Trade-offs
  • Hollow-sounding if undampened
  • Least premium feel
Wood
Warm look

A wooden case (often walnut or oak) gives a warm, organic aesthetic unlike anything else. Acoustics vary by wood and build.

Pros
  • Beautiful, unique look
  • Warm aesthetic
  • Pleasant to the touch
Trade-offs
  • Acoustics less predictable
  • Can warp / needs care
FR4 / sandwich
Niche

Built from FR4 (fibreglass PCB material), often as a layered "sandwich". Lightweight, affordable and with a distinctive clacky sound. Common on DIY and ergo boards.

Pros
  • Lightweight & cheap
  • Distinctive sound
  • Great for DIY/ergo
Trade-offs
  • Utilitarian look
  • Less rigid than metal
