SK87 75% Wireless Gaming Keyboard QMK/VIA - CNC Aluminum

In this review the SK87 75% Wireless Gaming Keyboard is examined for gamers and keyboard enthusiasts who want a premium, compact board with deep customization. The single biggest reason to consider it is the combination of a full CNC aluminum case with programmable QMK/VIA support and tri-mode connectivity, which together deliver a solid build, highly personalizable layouts, and the freedom to switch between Bluetooth, 2.4GHz, and wired use. For anyone who values tactile feel and strong RGB presentation in a 75% footprint, this keyboard stands out.

Key Features

• CNC aluminum case: The full aluminum body with anodized finish and crack design lets RGB shine through while giving the keyboard a durable, weighty feel.
• QMK/VIA programmable: Open-source firmware support makes it straightforward to remap keys, set macros, and save custom layouts for macOS, Windows, and Linux (remaps applied in wired mode).
• Tri-mode connectivity: Toggle between Bluetooth 5.0, 2.4GHz wireless, and USB-C wired to connect multiple devices and switch quickly for multitasking.
• Hot-swappable switches: The PCB supports 3-pin and 5-pin hot-swap switches so users can change switch types without soldering.
• Pre-lubed POM linear switches: Custom linear POM switches arrive pre-lubed for a smooth, fast response and a creamy FR4 feel under the keys.
• RGB and transparent keycaps: South-facing LEDs with glossy PC transparent keycaps produce bright, even lighting and vivid color effects.

Who It's For

The SK87 suits gamers and creators who want a compact 75% layout with premium materials and deep customization. It is well suited to users who value a solid, aluminum build and plan to use programmable layers or macros via QMK/VIA, and who appreciate strong RGB for streaming or a colorful desk setup.

People who prefer ultra-light, ultra-portable keyboards or who want a stock switch experience without any inconsistency in lubing might look elsewhere; some users report mixed experience with weight and occasional variability in switch lubing that can affect actuation feel.
