Compact Mini-ITX Case for Portable Builds

The Thermaltake TR100 is an 18.9-litre Mini-ITX chassis built from SPCC steel with a mesh side panel. It targets users who want a small-footprint system that can be moved between home and travel without sacrificing component headroom. Two internal 2.5-inch drive bays and three expansion slots provide essential storage and add-in card capacity.

Upgrade Path from Larger Towers

Builders moving down from mid-tower or full-tower cases gain a case that fits a 360 mm graphics card, a top-mounted 280 mm radiator and an SFX or SFX-L power supply up to 130 mm long. The jump is worth it when desk space or portability outweigh the loss of 3.5-inch drive bays and the tighter 68 mm CPU cooler limit. A PCIe 4.0 riser cable and removable PCIe bracket with integrated GPU brace are included to ease the transition.

Limits of the Mini-ITX Form Factor

The single-chamber layout restricts motherboard choice to Mini-ITX only and caps CPU cooler height at 68 mm, ruling out most tower air coolers. Power supply length stops at 130 mm, so standard ATX units will not fit. Top fan mounts accept 120 mm or 140 mm fans in one- or two-fan arrays, but no front, bottom or rear mounts exist. The mesh panel aids airflow, yet the compact volume means thermal headroom remains tight under sustained loads.

Questions about this item

Will a full-length graphics card fit inside this compact chassis?

The case allows graphics cards up to 360 mm long, so most full-size models will fit as long as they stay within that limit.

What size power supply is required for this build?

Only SFX or SFX-L units up to 130 mm in length are supported; standard ATX power supplies will not fit.

How much CPU cooler clearance does the TR100 provide?

You have 68 mm of height available, which accommodates many low-profile air coolers and thin AIO cold plates.
