Compact ITX chassis in Hydrangea Blue

The TR100 is an 18.9-litre Mini-ITX enclosure finished in Hydrangea Blue with a steel SPCC frame and a mesh side panel. Its dual-chamber layout separates the GPU zone from the motherboard tray, keeping cable runs short and airflow direct. The case ships with a PCIe 4.0 riser cable and a removable PCIe bracket that includes an integrated GPU brace. No fans are pre-installed, so the builder chooses the exact cooling configuration.

Builders who value portability

The small footprint and carry-friendly dimensions suit LAN events or a living-room setup where space is tight. The 360 mm GPU limit and 280 mm top radiator support accommodate high-end components in a compact volume. Users needing more than two 2.5-inch drives, a full-size ATX power supply, or a CPU cooler taller than 70 mm should consider a larger enclosure. Liquid-cooling loops with multiple radiators will also find the interior restrictive.

CPU cooler clearance capped at 70 mm

The 70 mm height restriction is the single dimension that determines whether a chosen cooler will fit. Most tower coolers exceed this limit, so low-profile or all-in-one liquid coolers with a 280 mm radiator become the practical options. Verify the exact height of any air cooler before purchase; even a few millimetres over 70 mm will prevent the side panel from closing.

Questions about this item

Which version of the TR100 should I choose for a portable Mini-ITX build?

The Hydrangea Blue model is the single variant offered; it measures 15.4" x 7.1" x 11.6", weighs 18.9 litres and supports Mini-ITX boards with two 2.5" drive bays.

What does the 360 mm GPU clearance mean once the card is installed?

It allows graphics cards up to 360 mm long, so most full-size dual- and triple-fan GPUs fit while leaving room for the included PCIe 4.0 riser cable and integrated brace.

How does the PCIe 4.0 riser affect bandwidth in practice?

The supplied riser carries PCIe 4.0 signals from the motherboard slot to the vertical GPU bracket, letting modern cards operate at their native link speed without an extra cable purchase.
