Updated on Oct. 27, 2026 in Computers
Thermaltake has released the Arcus 380 TG ARGB, a new mid-tower chassis featuring a one-piece curved tempered glass panel. The case supports back-connect motherboards and provides room for extensive cooling configurations.
Why it matters
The Arcus 380 TG ARGB reflects the ongoing industry trend toward hidden-cable designs by integrating back-connect motherboard support. This shift allows for cleaner builds by routing connectivity behind the main component tray.
The chassis supports high-performance components, including graphics cards up to 430 mm in length and CPU air coolers up to 160 mm in height. Users can mount top radiators measuring up to 360 mm or 280 mm.
The players
Thermaltake
A hardware manufacturer specializing in cooling solutions, power supplies, and PC enclosures for high-end systems.
The details
The Arcus 380 TG ARGB utilizes a dual-chamber structure that isolates power supply and cable management from the primary component area. It is compatible with Mini-ITX, Micro-ATX, and ATX motherboards, including those with rear-facing headers. This back-connect motherboard compatibility allows cables to be positioned behind the motherboard tray, reducing visible clutter within the main glass-paneled display area.
