As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The Thermaltake TR100 Mini-ITX SFF Case offers a compact 18.9-liter chassis with 360mm GPU clearance and an included PCIe 4.0 riser cable. If you are looking beyond the Thermaltake TR100 Mini-ITX SFF Case alternatives, you might want a different form factor or connectivity option. This case supports Mini-ITX motherboards and 280mm radiators, making it suitable for tight spaces. However, its specific dimensions and weight may not fit every desk setup. Some users prefer a lower profile or a different material for their build. Others may need support for standard ATX power supplies instead of SFX units. The alternatives were chosen because their specs overlap with the original. They share the Mini-ITX motherboard support and small form factor design. Each option provides a unique combination of size, connectivity, and component compatibility. You can compare these choices to find the best fit for your specific hardware needs. The list includes cases with varying dimensions and weights to suit different preferences. Some models emphasize portability, while others focus on airflow or visual appeal. All options listed here are designed for Mini-ITX builds. They offer practical solutions for users who need a compact chassis without sacrificing component support. This guide helps you navigate the available choices based on published specifications.
How these cases differ from the TR100
SilverStone Slim Mini-ITX Case with Handle
The SilverStone Slim Mini-ITX Case measures 3.43 inches in height, making it significantly lower profile than the 14-inch Thermaltake TR100. This design prioritizes horizontal placement, which suits tight spaces where the TR100’s vertical footprint would not fit. You lose the 360mm GPU clearance and included PCIe riser cable found in the TR100. Instead, you gain a lighter 7.72-pound chassis with a built-in handle for easier transport. This case is ideal if you need a portable Mini-ITX build that uses an SFX power supply rather than the larger units supported by the TR100.
Cooler Master NR200P V2 Mini-ITX Case
The Cooler Master NR200P V2 features a tempered glass side panel, offering visual appeal that the TR100’s dual-chamber design does not emphasize. It is slightly narrower at 7.28 inches wide compared to the TR100’s 17.3 inches, creating a more vertical tower look. While both cases support 280mm radiators, the NR200P V2 focuses on showcasing internal components through its glass panel. It weighs 10.9 pounds, similar to the TR100’s 10.7 pounds. You should pick this alternative if you prioritize aesthetics and vertical GPU mounting in a compact footprint over the specific component clearance options of the TR100.
SSUPD Meshroom S V2 SFF Mini-ITX Case
The SSUPD Meshroom S V2 is much smaller at 15 liters, compared to the 18.9-liter TR100. It weighs only 6.83 pounds, making it significantly lighter. This case supports 200mm fans and offers Type-C connectivity, features the TR100 lacks. It provides versatile motherboard support, potentially accommodating ATX boards in addition to Mini-ITX, whereas the TR100 is strictly Mini-ITX. You give up the included PCIe riser cable and the specific 360mm GPU clearance of the TR100. Choose this if you need strong airflow and modern I/O in a highly compact chassis.
SilverStone Small Form Factor Mini-ITX Case
The SilverStone SG13B-Q supports standard ATX power supplies, unlike the TR100 which requires SFX or SFX-L units. It measures 12 inches wide and 10 inches high, differing from the TR100’s wider, taller profile. This case weighs 6 pounds, making it lighter than the 10.7-pound TR100. It prioritizes component compatibility over extreme compactness, offering a practical layout for Mini-ITX parts. You do not get the 360mm GPU clearance or the included PCIe riser cable. This alternative is best for users who want a reliable chassis without needing excessive depth and prefer standard ATX power supplies.
SGPC 5L Portable Mini-ITX Case
The SGPC K39 is a 5-liter case, drastically smaller than the 18.9-liter TR100. It measures 4.7 inches wide and 8.7 inches high, fitting into very tight spaces. Weighing only 4.14 pounds, it is the lightest option here. This dense layout is for experienced builders who do not mind sourcing their own riser cable, as the TR100 includes one. You sacrifice the generous 360mm GPU clearance and 280mm radiator support of the TR100 for extreme portability. Pick this if you need a compact gaming chassis with modern I/O and prioritize size over ease of assembly.
HYTE Revolt 3 Mini-ITX Case with Handle
The HYTE Revolt 3 provides full side access, a feature not highlighted in the TR100’s dual-chamber design. It weighs 11 pounds, slightly heavier than the TR100’s 10.7 pounds. The Revolt 3 is 7 inches wide and 16.1 inches high, offering a tall, narrow profile compared to the TR100’s broader stance. It includes modern connectivity options for compact builds. You give up the included PCIe riser cable and the specific thermal clearance metrics of the TR100. This case is suitable if you prioritize component accessibility and portability in a small footprint, needing easy side access for maintenance.

Frequently asked questions
Which Mini-ITX case supports the largest graphics cards?
The Thermaltake TR100 offers 360mm GPU clearance, which is the largest specified support among the listed options. This allows you to install high-end, bulky graphics cards without fitting issues. Other cases like the Cooler Master NR200P V2 and SSUPD Meshroom S V2 list 280mm radiator support but do not specify GPU length limits, making the TR100 the clear choice for large cards.
What is the most portable Mini-ITX case on this list?
The SGPC K39 is the most portable option with a compact 5L volume and a weight of just 4.14 pounds. Its small dimensions of 4.7 by 7.7 by 8.7 inches make it easy to carry. While the SilverStone Slim Case includes a handle, the SGPC K39’s significantly smaller footprint and lighter weight make it the best choice for maximum portability.
Does any case include a PCIe riser cable?
Yes, the Thermaltake TR100 includes a PCIe 4.0 riser cable in the box. This is useful for vertical GPU mounting in tight spaces. The SGPC K39 requires you to source your own riser cable. None of the other listed cases, including the SilverStone Slim and Cooler Master NR200P V2, mention including a riser cable with their chassis.
Which case has a tempered glass side panel?
The Cooler Master NR200P V2 features a tempered glass side panel. This design choice highlights internal components for users who prioritize visual appeal. The other cases listed, such as the SilverStone Slim and SSUPD Meshroom S V2, do not specify tempered glass in their attributes, focusing instead on mesh or solid panel designs for airflow or durability.
Which cases support ATX power supplies?
The SilverStone SG13B-Q is explicitly noted for supporting standard ATX power supplies. This makes it practical for builders who want to use readily available PSUs. The SilverStone Slim Mini-ITX Case is specified for SFX PSUs. The Thermaltake TR100, Cooler Master NR200P V2, and others do not list ATX PSU support in their provided data, so assume they use SFX or proprietary units.
What is the lightest case available?
The SGPC K39 is the lightest case at 4.14 pounds. It is followed by the SilverStone SG13B-Q at 6 pounds and the SSUPD Meshroom S V2 at 6.83 pounds. The Thermaltake TR100 is significantly heavier at 10.7 pounds. If you need a lightweight build for frequent transport, the SGPC K39 offers the lowest weight among these Mini-ITX options.
Does the SSUPD Meshroom S V2 have USB Type-C?
Yes, the SSUPD Meshroom S V2 includes USB Type-C connectivity. This modern port is listed in its attributes alongside 200mm fan support and 280mm radiator compatibility. This feature provides faster data transfer and versatile peripheral connections for your compact gaming build, distinguishing it from cases that only list standard USB ports or do not specify connectivity options.
