Thermaltake TR100 SFF Chassis - Compact mITX Travel Case

In this review the Thermaltake TR100 SFF Chassis is assessed as a compact, travel-friendly mITX enclosure built for users who need desktop-level GPU and cooling support in a small footprint. The single biggest reason to consider this case is its balance of portability and component compatibility: at just 18.9 liters it still accepts long graphics cards and sizable radiators thanks to a thoughtful dual chamber layout and an included PCIe 4.0 riser. For builders who want a tidy, fairly straightforward small form factor experience, the TR100 delivers.

Key Features

• Small footprint: The 18.9 liter volume keeps the chassis highly portable and easy to fit on a desk or in luggage for travel.
• mITX optimized: Dual chamber design separates power and storage routing so small builds remain organized and compatible with mini-ITX motherboards.
• Large GPU clearance: With up to 360mm GPU support and a removable PCIe bracket, modern full-length cards install cleanly despite the small case size.
• Cooling options: Supports up to a 280mm radiator to enable serious liquid cooling for compact gaming rigs or workstation builds.
• Included PCIe 4.0 riser: The supplied riser cable meets current GPU bandwidth needs and simplifies mounting in the SFF layout.
• Build convenience: Magnetic side panels and an integrated GPU brace make assembly and maintenance quicker and more secure.

Who It's For

The TR100 is aimed at mITX builders who want to run full-size GPUs or water cooling in a very small case, such as LAN attendees, content creators with limited desk space, or anyone who values portability without sacrificing performance. Its combination of a removable PCIe bracket and included riser cable reduces the friction typically associated with SFF builds.

Those who should look elsewhere include users who need large drive cages, extremely tall air coolers beyond 68mm, or full tower-level expandability. If you require many internal 3.5 in drives or a full ATX motherboard, a larger chassis will be a better fit.

Pros & Cons

Pros

• Well balanced between size and component capacity, supporting 360mm GPUs in an 18.9 liter shell.
• Includes a PCIe 4.0 riser and removable PCIe bracket to simplify installation and keep bandwidth compatible with modern cards.
• Good cooling potential with support for a 280mm radiator and thoughtful dual chamber layout for cable routing.
• Magnetic side panels and integrated GPU brace improve accessibility and secure the build.

Cons

• CPU cooler clearance is limited to 68mm, which rules out some taller air coolers and may force liquid solutions for high TDP CPUs.
