Thermaltake TR100 Mini-ITX Hydrangea Blue PC case CA-11A-00SFNN-00

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.
