Japanese PC maker MOUSE COMPUTER has announced four new gaming desktops under its G TUNE and NEXTGEAR brands at Tokyo Game Show 2026, held at Makuhari Messe. The lineup includes a quiet desktop built around a mobile-class processor and high-end models with dual liquid cooling for stable overclocking. All four models went on sale at noon on September 17.

A Mobile CPU Brings Quiet Operation to the Desktop

Under the NEXTGEAR brand, MOUSE COMPUTER introduced two models, the JG-I5G60 and JG-I5G7L, both built around Intel's Core Ultra 5 processor 245HX, a chip originally designed for laptops. By repurposing a low-power mobile processor for a desktop chassis, the company keeps heat output down while still delivering solid processing performance. Both models use a semi-fanless design in which the case fans stop completely under light workloads, so everyday tasks such as browsing or video playback stay nearly silent.

The JG-I5G60 pairs the CPU with a GeForce RTX 5060, while the JG-I5G7L steps up to a liquid-cooled, factory-overclocked GeForce RTX 5070. Both come with 16GB of memory and a 500GB Gen4 NVMe SSD. Pricing starts at 239,800 yen for the JG-I5G60 and 349,800 yen for the JG-I5G7L, with both available from noon on September 17.

Dual Liquid Cooling Keeps High-End Overclocks Stable

On the higher-end G TUNE side, MOUSE COMPUTER added the FZ-I5G7L and FZ-I7G7L. They use Intel's Core Ultra 5 processor 250K Plus and Core Ultra 7 processor 270K Plus respectively, and both pair with a liquid-cooled, factory-overclocked GeForce RTX 5070. An optional dual liquid cooling system, developed with cooling specialist Asetek, is designed to sustain higher overclocked performance while keeping noise levels down.

Both models come with 32GB of memory and a 1TB Gen4 NVMe SSD. The FZ-I5G7L starts at 569,800 yen and the FZ-I7G7L at 589,800 yen, and both also launched at noon on September 17.

A Cloud Gaming Tablet Dock, Shown as a Concept

At its show floor booth, MOUSE COMPUTER also displayed a pre-production tablet docking station as a reference exhibit. The concept pairs the company's existing mouse M2 tablet with a dedicated dock, letting users stream demanding, high-end games through a cloud gaming service wherever they have an internet connection. The dock consolidates controller ports on its own side, so the tablet itself can still be used normally on its own. No release date has been set, and the device remains a concept still in development.

Summary

To coincide with Tokyo Game Show 2026, MOUSE COMPUTER rolled out a quiet-focused NEXTGEAR lineup built around a repurposed mobile CPU alongside higher-end G TUNE models that use dual liquid cooling to keep overclocked performance stable. The company also showed off a cloud gaming tablet dock concept at its booth, pointing to a broader product line that covers both stationary and on-the-go play. All four new desktop models have been on sale since noon on September 17.
