Reatan S6 Mini Gaming PC with i5-12450H - Compact 4K Mini PC

In this review the Reatan S6 Mini Gaming PC is examined as a compact, high-performance mini desktop aimed at users who need serious multitasking and display flexibility in a small footprint. The single biggest reason to consider the S6 is its 12th-generation Intel Core i5-12450H processor paired with 16GB DDR4 and a 512GB NVMe SSD, which together deliver noticeably faster responsiveness for content creation and light gaming than typical NUC-class systems. It makes a compelling choice where space is limited but real CPU power and multiple 4K outputs are required.

Key Features

• 12th-gen i5 Performance: The Intel Core i5-12450H with 8 cores and 12 threads provides strong single- and multi-threaded performance for photo editing and video rendering tasks.
• Expandable Memory and Storage: Ships with 16GB DDR4 and a 512GB M.2 NVMe SSD, and includes extra slots to upgrade to up to 64GB of RAM and additional M.2 storage for large projects.
• Triple 4K Display Support: Multiple display outputs including HDMI 2.0, DP and USB-C (with DP) let users run up to three 4K screens to improve productivity and workspace organization.
• Dual Gigabit Networking: Two RJ45 ports support link aggregation or separate network paths, useful for advanced networking setups or dual-network access.
• Efficient Cooling: A silent fan and multi-layer cooling structure keep temperatures and noise low during prolonged workloads, preserving sustained performance.
• Compact and Portable: The small chassis (about 5.08 x 4.84 x 1.73 in) saves desk space and is easy to move between workstations or locations.

Who It's For

The Reatan S6 is well suited to creators and professionals who need a compact system with strong CPU performance for tasks like Photoshop multi-layer editing and Premiere Pro rendering, plus the ability to drive multiple 4K displays. It also fits small office environments where dual LAN and versatile port options improve connectivity and docking workflows.

It is less appropriate for buyers seeking the smallest fanless mini PC or a system built primarily for high-end gaming GPUs; those users should look for purpose-built gaming desktops or ultra-compact fanless units if absolute silence and discrete graphics are required.

Pros & Cons

Pros

• Strong CPU performance from the i5-12450H for multitasking and content creation.
• Good upgrade path with extra memory and M.2 slots allowing up to 64GB RAM and additional SSD capacity.
• Multiple 4K-capable outputs and full-function USB-C simplify multi-monitor setups and cabling.
• Robust port selection including dual Gigabit LAN for flexible networking.

Cons

• Not aimed at users who need a discrete GPU for high-end gaming or GPU-accelerated workflows.
• The active cooling design means it is not fully silent under sustained heavy load.
