What stands out
- 18.9-liter volume optimized for mini-ITX motherboards
- 360mm maximum GPU length clearance for large cards
- Support for 280mm radiators for liquid cooling
- Includes a PCIe 4.0 riser cable for easy GPU connection
Who it fits
Good fit for
This case suits builders who want a compact system for home use or travel. If you need a small footprint but still want to fit a large graphics card, the 360mm clearance is key. It is also good for those who prefer liquid cooling, as it supports 280mm radiators. The included riser cable helps those who want a clean install without buying extra parts. The dual-chamber design helps keep cables organized in the limited space.
Who should skip it
You should look elsewhere if you plan to use a standard ATX or micro-ATX motherboard, as this case only supports mini-ITX. It may also not suit those who need extensive drive bays or multiple expansion slots, given its small 18.9-liter volume. If you require a full-tower case for maximum airflow or component compatibility, this SFF chassis is too restrictive. Additionally, users who prefer horizontal orientations might find the vertical tower design less appealing.
Verdict: The Thermaltake TR100 offers a practical solution for mini-ITX builds with generous clearance for GPUs and coolers. Its included riser cable and compact design make it a solid choice for space-conscious builders.
Thermaltake TR100 Key Specs
Case Volume: 18.9 Liters
This volume indicates a Small Form Factor chassis with a very compact footprint. You save desk space and reduce shipping weight when moving the rig. Compare this to mid-tower cases that exceed 40 liters. The tight space requires careful component selection to ensure all parts fit without overcrowding the interior.
Motherboard Support: mITX
The case accepts only Mini-ITX motherboards, which are the smallest standard PC boards. This limits your expansion slots but fits the compact design. You cannot install larger ATX or Micro-ATX boards. This restriction ensures the dual-chamber layout remains organized and allows for the small overall dimensions of the chassis.
Max GPU Length: 360mm
You can install graphics cards up to 360mm long. This clearance covers most modern high-performance cards. Check your specific GPU dimensions before buying, as some models exceed this limit. This length allows for powerful gaming rigs within a small case, provided you balance it against CPU cooler height restrictions.
Radiator Support: 280mm
The case accommodates liquid cooling radiators up to 280mm in size. This helps manage heat from powerful components in the tight 18.9-liter volume. You can mount these radiators in various positions to optimize airflow. Larger 360mm radiators may not fit, so verify your cooling needs against this specific size limit.
Compact Design and Layout Analysis
According to the listing, the Thermaltake TR100 measures 11.6 inches in height and features a dual-chamber design. This layout separates the power supply and motherboard from the graphics card. You benefit from organized airflow and easier cable management in such a tight 18.9-liter volume. The small form factor makes it ideal for users who need a portable build for travel or limited desk space. The compact footprint reduces the overall size without compromising essential component support.
The case supports Mini-ITX motherboards and includes a removable PCIe bracket for straightforward GPU installation. You also get an integrated GPU brace for added security during transport. The listing notes a 360mm GPU clearance and 280mm radiator support. These dimensions allow you to install modern high-performance components despite the small size. An included PCIe 4.0 riser cable facilitates easy installation and meets modern bandwidth requirements. You can choose from various colors like Matcha Green or Hydrangea Blue. The finish options let you match your personal style while maintaining a professional look. This design balances portability with the ability to house powerful hardware. You get a practical solution for small spaces without sacrificing performance potential. The removable bracket simplifies upgrades and maintenance tasks. Overall, the build focuses on functionality and compact efficiency for mini-ITX enthusiasts.
Setup and Everyday Use
The Thermaltake TR100 is designed for users who value portability and a compact footprint. Its 18.9-liter volume makes it easy to move between locations or place on a small desk. The listing highlights a dual-chamber design that helps organize internal components. This layout separates the power supply from the motherboard and graphics card. You benefit from a cleaner interior that simplifies cable routing.
Installation is straightforward thanks to included accessories. The package includes a PCIe 4.0 riser cable. This cable supports modern graphics cards by providing necessary bandwidth. It also facilitates easier installation within the tight space. The case features a removable PCIe bracket. This allows you to install your GPU without removing other components. An integrated GPU brace adds stability for heavier cards.
Thermal support is robust for its size. You can install a 280mm radiator in the front. The case also supports SFX and SFX-L power supplies. CPU cooler clearance is 68mm, which limits you to low-profile coolers. Graphics card length reaches 360mm, accommodating most high-end models. The Mini-ITX motherboard support keeps the build small. Daily use involves managing heat in a confined space. Proper fan placement is essential. The compact design reduces desk clutter. It is suitable for home use or travel. You get a portable system that does not compromise on component compatibility.
Before You Buy This Case
You need to verify component compatibility before purchasing. The case supports Mini-ITX motherboards, so ensure your board fits this form factor. Check that your GPU is under 360mm in length. The listing notes support for SFX and SFX-L power supplies, so you must buy one separately. CPU coolers must not exceed 68mm in height. You should also confirm your radiator fits within the 280mm limit. The included PCIe 4.0 riser cable simplifies installation, but verify it works with your specific graphics card. This compact 18.9-liter chassis suits users prioritizing portability and desk space. It differs from larger mid-tower options by offering a dual-chamber layout for better airflow management. Regularly clean dust filters to maintain performance. This case fits well alongside other small form factor choices if you value a small footprint. Always double-check clearances for all internal parts to avoid fitment issues during assembly.
Check before you buy
- Verify your motherboard is Mini-ITX compatible.
- Ensure GPU length is under 360mm.
- Confirm CPU cooler height is under 68mm.
- Purchase an SFX or SFX-L power supply.
