AI Verdict
This is an 11.5L S.F.F. slim chassis with a 300W TFX PSU and 4 low-profile expansion slots for Micro-ATX or Mini-ITX builds.
This case is a situational fit due to its specific 11.5L S.F.F. slim chassis and integrated 300W TFX PSU. It works for very specific, low-power builds but imposes significant limitations on component choice and upgrade paths.
If you need more power or flexibility for expansion cards, look for cases that support standard ATX PSUs and full-height expansion slots.

Pros
- Compact 11.5L S.F.F. slim chassis design for space-constrained setups.
- Supports both Micro-ATX and Mini-ITX motherboards, offering some flexibility.
- Includes a legacy 5.25" external bay for optical drives or other peripherals.
- Front I/O panel features two USB 3.0 ports and two USB 2.0 ports for connectivity.
Cons
- Integrated 300W TFX PSU significantly limits component selection, especially for graphics cards.
- Only supports low-profile expansion cards, restricting GPU and other add-in card options.
- Air cooling in an 11.5L chassis can lead to thermal challenges and increased fan noise under load.
- Limited internal storage with two 3.5" bays and one 2.5" bay.
Dimension Scores
The included 300W TFX PSU offers limited power output, restricting component choices for anything beyond basic systems.
Air cooling in a compact 11.5L chassis with a small PSU fan is likely to produce noticeable noise, especially under load.
Constructed from a mix of plastic and metal, the build quality is average for its price point.
The ultra-small form factor (11.5L) inherently makes cable routing and management extremely challenging, potentially hindering airflow.
Best For
- Office workstations utilizing integrated graphics.
- Home Theater PC (HTPC) builds where a slim profile is essential.
- Basic home computers for web browsing and productivity.
- Systems needing a legacy 5.25" optical drive in a compact form factor.
Not Recommended For
- Gaming PCs or systems requiring dedicated high-performance graphics cards.
- High-performance workstations with power-hungry CPUs or multiple storage drives.
- Users prioritizing silent operation due to potential small fan noise.
- Builders who require full-height expansion slots for specific hardware.
Watch Out For
- The 300W TFX PSU is a proprietary form factor, making upgrades difficult and limiting power for modern components.
- Maximum CPU cooler height is restricted, typically around 72mm, limiting aftermarket cooler options.
- Graphics card length is severely limited, often to around 195mm, and only low-profile cards fit.
- Cable management is challenging in the compact 11.5L interior, potentially impeding airflow.
- Users report the case is 'not perfect but it's usable,' indicating compromises in design or build experience.

What Buyers Say
Users often choose this case for its compact 11.5L S.F.F. slim chassis when specific mounting locations are necessary. However, this small size comes with significant trade-offs, particularly regarding power supply limitations and restricted expansion options. The integrated 300W TFX PSU is a frequent point of concern, as it severely limits the types of components that can be installed. Builders also find that only low-profile expansion cards are supported, which means high-performance graphics cards are out of the question. The tight interior space makes building and cable management a difficult task.
“Needed something tiny for a server, this fit the spot, but man, getting everything in there was a puzzle and the power supply is barely enough.”
Common Praise
- Compact 11.5L S.F.F. chassis fits into tight spaces.
- Includes a pre-installed 300W TFX power supply.
- Supports both Micro-ATX and Mini-ITX motherboards.
- Features front panel USB 3.0 ports.
Common Complaints
- The 300W TFX PSU is underpowered for many modern components and difficult to upgrade.
- Only low-profile expansion slots are available, severely limiting GPU choices.
- Tight interior space makes building and cable management frustrating.
- Potential for increased noise due to small fans in a confined space.
Ownership Tips
- Realized the 300W TFX PSU is a bottleneck for even modest component upgrades.
- Discovered that CPU cooler height is extremely restrictive, requiring specific low-profile coolers.
- Found that cable routing is a constant battle, impacting airflow and component temperatures.
- Noticed the small fans, especially the PSU fan, can become audible under sustained load.
- Learned that finding compatible low-profile graphics cards with any real performance is a challenge.
Frequently Asked Questions
Can I upgrade the power supply?
Yes, but you are limited to TFX form factor power supplies, which are less common and often more expensive than standard ATX PSUs.
What kind of graphics card can I use?
You can only use low-profile graphics cards. The maximum length is typically around 195mm, and the card must be single-slot or fit within the low-profile slot constraints.
Is this case quiet?
Air cooling in a small 11.5L chassis, combined with the integrated TFX PSU fan, can generate noticeable noise, especially when components are under load.
How many drives can this case accommodate?
It supports one external 5.25" bay, one external 3.5" bay, two internal 3.5" bays, and one internal 2.5" bay.
Does it have USB 3.0 ports?
Yes, the front I/O panel includes two USB 3.0 ports and two USB 2.0 ports.
Buying Guide
When considering an ultra-small form factor case like this, you need to understand that its compact size dictates significant compromises. You won't be building a gaming rig or a high-end workstation here. The integrated 300W TFX power supply and limited low-profile expansion slots mean your component choices will be severely restricted, primarily to integrated graphics and low-power CPUs. Expect a challenging build process due to the tight interior and potentially higher noise levels from smaller fans.
11.5L S.F.F. Slim Chassis
This refers to the case's extremely small volume (11.5 liters) and slim design. It's like trying to fit a desktop PC into a shoebox, meaning every component must be compact, and airflow is inherently limited.
300W TFX PSU
This is the included power supply, rated for 300 watts, and it uses a specific 'TFX' form factor. Think of it as a small, specialized engine; it's enough for basic tasks but won't power a high-performance car, and finding a more powerful replacement is difficult.
4x Low Profile Slots
These are the slots for adding expansion cards, like a graphics card. 'Low profile' means they are half the height of standard cards, severely limiting your options to very basic or specialized cards, unlike the full-sized cards found in most desktop PCs.
Alternatives
If this case doesn't fit your needs, look for cases that support standard ATX power supplies for more upgrade options, or cases with full-height expansion slots if you plan on using a dedicated graphics card.
