K66 Lite 8.4L Mini-ITX Case - Ultra-Compact Small Form Factor

In this review the K66 Lite is judged as a sensible choice for builders who need a truly compact Mini-ITX chassis with decent cooling headroom and a clean aesthetic. The single biggest reason to buy is the balance of very small footprint and sensible component support: it fits an SFX PSU, a 240mm-length GPU and up to a 135mm CPU cooler while keeping a tempered glass side panel and a pre-installed ARGB fan. That combination makes it a practical option for portable SFF projects where component compatibility and build quality matter.

Key Features

• Ultra-compact volume: The 8.4L footprint measures 240 x 160 x 220 mm, making it easy to place on a desk or pack for travel while still holding full-size components within specified limits.
• Durable construction: Steel panels of 1.0-1.5 mm thickness plus a 3 mm tempered glass side give a solid, premium feel and protect internal components.
• Useful front I/O: Dual USB 3.0 plus a Type-C port wired to a single 19-pin connector provide modern connectivity and up to 5 GB/s transfer speeds for external devices.
• Balanced cooling support: Supports up to a 135 mm air cooler or a 120 mm AIO with pump head clearance to 50 mm and space for 92 mm fans at top and rear for airflow tuning.
• Component compatibility: Accepts standard Mini-ITX motherboards up to 170 x 170 mm, SFX PSUs to 125 x 100 x 64 mm, and GPUs up to 240 x 45 mm to maximize performance in a small pack.
• Two-handle options: Ships with optional plastic and leather handles so users can choose a more utilitarian or premium carry style for portable builds.

Who It's For

The K66 Lite is aimed at enthusiasts building a small form factor gaming or workstation PC who need a compact case without sacrificing the ability to use a decent GPU and an SFX power supply. It suits people who value a tempered glass side panel and cleaner internal presentation alongside a pre-installed ARGB fan for a finished look.

It is less suitable for builders who require very long GPUs, SFX-L power supplies, or large custom water cooling loops; those users should look for a larger SFF or micro-ATX chassis that explicitly supports longer cards and SFX-L units.

Pros & Cons

Pros

• Compact 8.4L size that still accepts a 240 mm GPU and SFX PSU for powerful small builds.
• Sturdy steel construction and a 3 mm tempered glass side deliver a premium appearance and durability.
• Good cooling flexibility with support for up to 135 mm CPU coolers, a 120 mm AIO, and 92 mm fan positions.
• Front I/O includes USB 3.0 and Type-C via a 19-pin header for modern connectivity.

Cons

• Does not support SFX-L PSUs and has a strict 240 x 45 mm GPU limit, so component choices are constrained.
• Some users reported mixed impressions about the included screws, so expect to check fasteners during assembly.

Our Verdict

The K66 Lite delivers strong value for small form factor builders who need a compact, reasonably roomy Mini-ITX case with solid materials and modern I/O. It is a smart pick for portable gaming or compact workstations where the 240 mm GPU and SFX PSU limits are acceptable. For anyone requiring larger PSUs or longer graphics cards, a larger chassis will be a better choice.
