Alternatives to the Thermaltake TR100

SilverStone Slim Mini-ITX Case with Handle

The SilverStone Slim Mini-ITX Case with Handle differs by prioritizing extreme portability over raw internal volume. It measures 15 inches wide, 3.43 inches tall, and 14.6 inches long, weighing just 7.72 pounds. This slim profile supports 13-inch graphics cards and SFX power supplies, making it ideal for builders who need a carry handle and a low vertical footprint. Unlike the TR100, which offers 18.9 liters and 360mm GPU clearance, this case sacrifices internal space for a flat, travel-friendly design. You should choose this option if you frequently transport your PC and have shorter graphics cards, rather than needing the room for larger components found in the Thermaltake model.

Cooler Master NR200P V2 Mini-ITX Case

The Cooler Master NR200P V2 Mini-ITX Case offers 18.25 liters of volume, slightly less than the TR100’s 18.9 liters, but includes tempered glass side panels for visibility. It supports 280mm radiators and vertical high-end GPUs, similar to the TR100’s cooling capabilities. This case bundles a PCIe 4.0 riser cable, matching the Thermaltake’s inclusion of modern connectivity for GPU bandwidth. It measures 7.28 inches wide, 11.5 inches tall, and 14.7 inches long. You might prefer this alternative if you want a glass side panel to showcase components, as the TR100 focuses on a dual-chamber design without specified glass features. It is a strong choice for those seeking visibility alongside compact SFF performance.

SSUPD Meshroom S V2 SFF Mini-ITX Case

The SSUPD Meshroom S V2 SFF Mini-ITX Case packs a 15-liter mesh chassis that supports ATX motherboards, a significant difference from the TR100’s Mini-ITX-only design. It accommodates 4-slot GPUs and 280mm radiators, offering flexible cooling in a compact 6.57-inch wide, 14.3-inch tall, and 9.72-inch long frame. This case includes Type-C connectivity and supports 200mm fans, providing a different airflow strategy. You should consider this option if you need to build with an ATX motherboard or want mesh construction for maximum airflow, rather than the enclosed dual-chamber design of the TR100. It gives up Mini-ITX exclusivity for broader component compatibility in a similarly small footprint.

SilverStone Small Form Factor Mini-ITX Case

The SilverStone Small Form Factor Mini-ITX Case supports standard ATX power supplies, a key distinction from the TR100’s SFX and SFX-L PSU support. It measures 12 inches wide, 10 inches tall, and 14 inches long, weighing 6 pounds. This design allows for desktop hardware compatibility in a small enclosure, supporting 10.5-inch expansion cards. You should pick this alternative if you prefer using readily available ATX power supplies rather than the smaller SFX units required by the TR100. It offers a practical solution for builders who want to avoid sourcing specialized power supplies, though it may not support the same GPU lengths or radiator sizes as the Thermaltake model.

SGPC 5L Portable Mini-ITX Case

The SGPC 5L Portable Mini-ITX Case provides an ultra-compact 5.1-liter volume, significantly smaller than the TR100’s 18.9 liters. It measures 4.7 inches wide, 8.7 inches tall, and 7.7 inches long, weighing just 4.14 pounds. This case supports short graphics cards and Flex-1U power supplies, targeting experienced builders who prioritize desk space. It retains modern front-panel USB-C connectivity. You should choose this option if you need a portable build that fits in tight spaces, accepting the trade-off of limited GPU and power supply compatibility. It is not suitable for large components or 280mm radiators, unlike the more spacious Thermaltake TR100.

HYTE Revolt 3 Mini-ITX Case with Handle

The HYTE Revolt 3 Mini-ITX Case with Handle is a sturdy, portable option measuring 7 inches wide, 16.1 inches tall, and 9.9 inches long, weighing 11 pounds. It emphasizes side access and front I/O convenience for Mini-ITX gaming builds. Unlike the TR100, which includes a PCIe 4.0 riser cable, this case focuses on structural portability and ease of access. You should consider this alternative if you value a built-in handle and straightforward side panel removal for component installation. It offers a different approach to portability compared to the TR100’s compact dual-chamber design, catering to builders who prioritize physical handling and accessibility over maximum internal volume.
