AI Verdict
This 11.5L S.F.F. chassis with a 300W TFX PSU supports Micro-ATX/Mini-ITX boards and 4 low-profile slots, suitable for compact, low-power builds.
This case is a situational fit for specific builds that prioritize a small footprint and low power consumption. The 11.5L S.F.F. chassis and included 300W TFX PSU dictate component choices, making it unsuitable for high-performance parts.
If you need more power or space for a dedicated GPU, look for a Micro-ATX case that supports standard ATX power supplies and has a GPU clearance of at least 250mm.

Dimension Scores
The 300W TFX PSU is adequate for basic systems but severely limits component selection for anything requiring more power.
The case relies on air cooling and has an 80mm system fan, with some users reporting quiet operation for low-power builds.
Users generally report the design and build quality as well-received, with "good build quality" and "more positive surprises than negative".
Cable management is consistently described as a "headache" and challenging due to the small internal volume.
Best For
- Building a compact office PC with integrated graphics.
- Creating a home theater PC (HTPC) with minimal components.
- Housing a small server or network attached storage (NAS) with multiple drives.
- Systems requiring only low-profile expansion cards.
Not Recommended For
- Gaming PCs with dedicated, full-size graphics cards.
- High-performance workstations needing powerful CPUs and cooling.
- Users who prioritize easy cable routing and tool-free installation.
Watch Out For
- The included 300W TFX PSU might be insufficient for anything beyond basic integrated graphics, with one user wishing for 350W or 400W.
- Maximum graphics card length is limited to 195 mm, severely restricting GPU options.
- The case lacks front USB-C or IR, despite being listed as optional features on some models.
- No instructions are included, making initial assembly potentially confusing for new builders.
- Cable management is a "headache" due to the small internal space.

Frequently Asked Questions
What type of motherboard does this case support?

Is the included power supply sufficient for a gaming PC?
The included 300W TFX PSU is generally not sufficient for gaming PCs with dedicated graphics cards, as it limits power and GPU options.
Can I install a full-size graphics card?
No, the case only supports low-profile expansion cards and has a maximum graphics card length of 195 mm.
Does this case have USB-C ports on the front?
This specific model does not come with front USB-C ports; it features two USB 3.0 ports instead.
Are there any tool-free features for installation?

Buying Guide
When looking at small form factor cases like this, you're trading expandability and ease of building for a compact size. The included power supply wattage is a hard limit on what components you can use, especially your CPU and any dedicated graphics card. Pay close attention to the maximum dimensions for components like GPUs and CPU coolers, as these cases are very restrictive.
wattage (300W)
This number tells you the total electrical power the included power supply can deliver to your components. Think of it like the engine size in a car; a smaller engine (lower wattage) means you can't carry as heavy a load (powerful components).
compatible (Micro ATX)
This refers to the size of the motherboard that will fit inside. Micro ATX is smaller than standard ATX, allowing for more compact builds but with fewer expansion slots.
Case Type (11.5L S.F.F Slim Chassis)
This indicates the overall volume and form factor of the case. 11.5 liters is very small, meaning internal space for components and airflow will be limited, similar to trying to fit a lot of furniture into a small apartment.
Expansion Slots (4x Low Profile Slots)
These are the openings for adding extra cards like graphics cards or network cards. "Low Profile" means you can only use shorter, thinner versions of these cards, not the full-sized ones you see in larger desktop PCs.
Alternatives
If you need more power for a dedicated graphics card or easier cable management, search for Micro-ATX cases that support standard ATX power supplies and have at least 250mm GPU clearance.
