Thermaltake TR100 SFF Chassis - Compact mITX Case for Travel

In this review the Thermaltake TR100 SFF chassis is examined as a small, travel-ready mITX case aimed at builders who need a compact footprint without sacrificing compatibility. The single biggest reason to consider the TR100 is its balance of portability and component room: at 18.9 liters it remains highly portable while still supporting full-length GPUs up to 360mm and 280mm radiators, making it a standout option for users who want a portable mITX build that can house high-performance parts.

Key Features

• Compact volume: The 18.9 liter chassis keeps a minimal footprint for easy transport and discreet placement at home or on the go.
• High GPU clearance: Support for GPUs up to 360mm means many modern cards will fit without forcing a compromise on performance choices.
• Radiator support: The ability to accommodate a 280mm radiator gives room for effective liquid cooling in a small case.
• Included PCIe 4.0 riser: The bundled PCIe 4.0 riser cable addresses modern GPU bandwidth needs and simplifies installation in the small layout.
• Removable PCIe bracket: A detachable bracket and integrated GPU brace make installing and securing long cards straightforward in a cramped interior.
• Travel-focused design: Magnetic side panels and a dual chamber internal layout speed builds and disassembly for travel or lan events.

Who It's For

The TR100 is best for mITX builders who prioritize portability but still want to use high-end GPUs or custom liquid cooling; content creators, gamers who travel, and anyone assembling a compact but capable system will appreciate the balance of space and features. The included PCIe 4.0 riser and removable bracket reduce the usual frustration of SFF assembly, while the magnetic panels and modest volume make it easier to move or store.

Those who need extensive drive bays, large air-cooled tower coolers taller than 68mm, or a full ATX motherboard should look elsewhere, as the TR100 is optimized for mITX layouts and SFX/SFX-L power supplies rather than large, multi-bay desktop configurations.

Pros & Cons

Pros

• Excellent component support for its size, including 360mm GPU clearance and 280mm radiator compatibility.
• Thoughtful accessories like a PCIe 4.0 riser cable and removable PCIe bracket ease installation.
• Well-built feel and clean aesthetics that customers note improve perceived build quality and cable management.
• Magnetic side panels and a dual chamber design make teardown and maintenance quick for travel.

Cons

• Limited height for tall air coolers (68mm CPU cooler clearance) means some tower coolers will not fit.
• As with many SFF cases, internal routing space is tighter than mid tower alternatives, which can challenge novice builders.
