Mouse Computer announced new gaming PC products on September 17th, coinciding with TOKYO GAME SHOW 2026. Sales will begin on the same day at noon, available through the Mouse Computer website, direct shops nationwide, GTune:Garage Osaka, telephone order desks, and corporate sales desks. The highlight this time is the new lineup of models introduced under two brands: G TUNE and NEXTGEAR. Prices start from ¥569,800 for the G TUNE FZ-I5G7L, ¥589,800 for the G TUNE FZ-I7G7L, ¥239,800 for the NEXTGEAR JG-I5G60, and ¥349,800 for the NEXTGEAR JG-I5G7L.

A key highlight common to both G TUNE and NEXTGEAR is Mouse Computer's original NVIDIA GeForce RTX 5070 liquid-cooled overclocked version, co-developed with MSI and Asetek. This liquid cooling system, featuring a 240mm radiator, is designed to efficiently dissipate GPU heat, stably deliver high performance during overclocking, and enhance quiet operation. Benchmarks reportedly showed up to 7.89% higher scores compared to air-cooled models, with the GPU temperature at 100% load being approximately 19°C lower, at 56°C. Users can also opt for dual liquid cooling, which independently cools the CPU and graphics card.

The G TUNE FZ-I5G7L features an Intel Core Ultra 5 Processor 250K Plus, 32GB of memory, and a 1TB NVMe Gen4x4 SSD, starting at ¥569,800. The higher-end G TUNE FZ-I7G7L comes with an Intel Core Ultra 7 Processor 270K Plus, also with 32GB of memory and a 1TB SSD, priced from ¥589,800. Both models come in a gray chassis and feature a tempered glass side panel.

NEXTGEAR makes its debut as the brand's first desktop PC to feature an Intel CPU. The NEXTGEAR JG-I5G60 combines an Intel Core Ultra 5 Processor 245HX from the mobile HX series with a GeForce RTX 5060, starting at ¥239,800. The higher-end NEXTGEAR JG-I5G7L pairs the same CPU with the liquid-cooled overclocked GeForce RTX 5070, starting at ¥349,800. Furthermore, it adopts semi-fanless case fans that can control rotation speed down to 0rpm, stopping the fans for enhanced quietness during low loads and increasing cooling performance as needed during high loads.

Purchase options are available from September 17th at noon onwards via the Mouse Computer website, direct shops nationwide, GTune:Garage Osaka, telephone order desks, and corporate sales desks. The G TUNE FZ-I5G7L and FZ-I7G7L models will also be on display at Mouse Computer direct shops nationwide from the same day.
