Despite minor hurdles like initial complexity and limited availability, the consensus is that the T1 delivers a remarkably well-designed, compact enclosure, fostering strong user satisfaction and community loyalty.
Know before you buy
The T1 accommodates graphics cards up to 325mm in length. Because it features a 3-slot expansion design, it is compatible with most high-end, triple-slot GPUs.
Yes, the T1 supports 240mm AIO liquid coolers. This allows you to maintain high performance for powerful CPUs despite the case's compact 9.95L footprint.
The case is designed for SFX and SFX-L form factor power supplies. Given the tight cable management space, modular SFX units are highly recommended for an easier build process.
Yes, the version 2.1 comes with an included PCIe 4.0 riser cable. This ensures full bandwidth support for modern graphics cards without needing to purchase additional accessories.
Due to its sandwich layout and small volume, the T1 is considered an enthusiast-level case. While the CNC-machined panels are high quality, the build process requires patience and careful cable management compared to larger mid-tower cases.
The T1 supports both standard Mini-ITX and Mini-DTX motherboards. This flexibility allows you to choose boards with more robust power delivery or additional features often found on DTX layouts.
