Compact Mini-ITX Chassis for Portable Builds

The Thermaltake TR100 is an 18.9-litre dual-chamber case designed for Mini-ITX motherboards and SFX power supplies. It targets enthusiasts who want a small-footprint system that remains easy to transport. A PCIe 4.0 riser cable is included to connect the graphics card in the separate GPU chamber.

Suits Builders Prioritising Portability

This case fits users who need 360 mm graphics-card clearance and up to 280 mm radiator support in a compact tower. It is not for builders who require 3.5-inch drive bays, ATX motherboard support, or CPU coolers taller than 68 mm. The lack of pre-installed fans also means you must supply your own cooling.

68 mm CPU Cooler Height Limit Decides Compatibility

The maximum CPU cooler height of 68 mm is the critical constraint for component selection. Only low-profile air coolers or thin AIO units will fit in the right chamber. Verify your cooler specification against this figure before purchase to avoid clearance issues.

Questions about this item

What motherboard form factor do I already need for the TR100 Gravel Sand case?

You need a Mini-ITX motherboard, as the case only supports that form factor.

Will my existing 360 mm long graphics card fit alongside the PCIe 4.0 riser cable in this chassis?

Yes, the case allows GPUs up to 360 mm in length and 70 mm thick, and the included riser cable routes the card into the left chamber.

How can I verify the case airflow is adequate after installing top fans and an AIO radiator?

Monitor CPU and GPU temperatures under load; the mesh side panels and support for two 120 mm or 140 mm top fans plus a 280 mm radiator are designed for strong thermal performance.
