What stands out
- Compact 8.1L volume with a handheld leather handle
- Three-sided mesh panels for improved air exchange
- Front I/O includes USB 3.0 Type-C port
- Supports SFX/SFX-L power supplies from 100-130mm
- Includes a PCIe 3.0 16X riser cable for GPU installation
Who it fits
Good fit for
You should choose this case if you need a small, portable gaming rig. It suits users who want a Mini-ITX build that fits in a backpack or small bag. The mesh panels help keep components cool in tight spaces. It is ideal for those who need USB Type-C connectivity on the front. If you have a low-profile CPU cooler and an SFX power supply, this chassis fits your parts perfectly. The included riser cable simplifies GPU installation in such a small space.
Who should skip it
Skip this case if you plan to use a standard ATX or Micro-ATX motherboard. It only supports Mini-ITX boards, so larger components will not fit. You should also avoid it if your graphics card exceeds 305mm in length or 55mm in height. The case has a strict 60mm limit for CPU fan height. If you need an ATX power supply, this unit is not compatible. The small volume means limited cable management space for bulky cables.
Verdict: The S300 is a highly portable Mini-ITX case for users who prioritize size and mobility. It offers decent airflow and modern connectivity for small form factor builds.
Key specs explained for S300
Case Volume: 8.1L
This volume indicates a very compact footprint. You get minimal internal space, which limits component selection. This size suits users prioritizing portability or desk space over expandability. When shopping, compare this to standard mid-towers that exceed 40L. You must choose small components to fit inside.
Motherboard Support: Mini-ITX
The case only accepts Mini-ITX motherboards, which are the smallest standard form factor. You cannot install larger ATX or Micro-ATX boards. This restriction simplifies cable management but reduces upgrade options. Check your motherboard size before buying. This spec defines the core build constraint for this case.
Max GPU Length: ≤ 305mm
Graphics cards must be 305mm or shorter to fit. Many high-end cards exceed this length. You need to measure your specific GPU before purchase. This limit affects cooling performance and card selection. Compare this to larger cases that support 350mm cards for more flexibility.
Side Panel: Mesh
Mesh panels allow air to flow freely into the case. You get better cooling for CPU and GPU components. This design helps dissipate heat during gaming sessions. Solid panels trap heat. Mesh is preferred for performance builds. Ensure you have adequate case fans to utilize this airflow.
Design and build quality
According to the listing, the S300 measures 12.2 by 5.3 by 7.6 inches. Its total volume is 8.1 liters. This compact footprint makes it easy to carry. The case weighs 4.41 pounds, which keeps it light for travel. A small leather handle sits on the top for portable use. You can move it between locations without difficulty.
The exterior uses pure aluminum wire drawing material for the front I/O area. Three-sided mesh panels cover the case. This design improves hot and cold air exchange. Better airflow helps keep components cool in such a tight space. The front panel includes a USB 3.0 Type-C port. This provides modern connectivity for peripherals. You can connect devices directly without adapters.
Inside, the layout supports Mini-ITX motherboards. The case holds SFX or SFX-L power supplies up to 130mm long. CPU fans must be 60mm or shorter. Graphics cards can be up to 305mm long. The height limit is 55mm, or 2.5 slots. A PCIe 3.0 16X riser cable is included. You must set your motherboard BIOS to GEN3 for the riser to work. This build focuses on small form factor gaming. It suits users who need a portable, high-performance system.
Setup and daily use notes
Setting up this KXRORS S300 case requires specific attention to component compatibility and BIOS settings. You must ensure your motherboard BIOS is set to PCIe Gen 3 speed if you use the included PCIe 3.0 16X riser cable. Failure to do so may prevent the computer from working. This step is critical for stable operation with 3.0 graphics cards. You will need a Mini-ITX motherboard measuring 170 by 170 mm. The case supports SFX or SFX-L power supplies with a length limit of 100 to 130 mm. Airflow is managed through three-sided mesh panels, which help exchange hot and cold air effectively. You should keep CPU fan height under 60 mm to fit inside the chassis. For graphics cards, the maximum length is 305 mm. The height is limited to 55 mm, which equals 2.5 slots, and the width cannot exceed 130 mm. The front I/O panel includes a USB 3.0 Type-C port for convenient connectivity. The case weighs 4.41 pounds, making it portable for travel. The leather handle on top aids in carrying. Daily use involves managing heat through the mesh design. The compact 8.1-liter volume means you have limited space for cables and components. You should plan your cable management carefully. The aluminum wire drawing material on the front adds durability. This setup is best for users who need a small, transportable gaming rig. It suits those who prioritize portability and specific compact component sizes over large expandability.
Key Considerations Before Purchase
Owning this compact case requires careful planning. You must verify your graphics card fits within the 305mm length and 55mm height limits. The included PCIe riser cable mandates Gen 3 motherboard settings, so check your BIOS compatibility before starting. You will need an SFX or SFX-L power supply, as standard units will not fit. CPU cooler height is capped at 60mm, restricting your cooling options significantly. Daily upkeep involves cleaning the three-sided mesh panels to maintain airflow, as dust accumulation can impact performance in such a small volume. This case suits users who prioritize portability and desk space over expandability. It contrasts sharply with larger mid-towers that offer more room for multiple drives and full-size components. If you need a stationary, high-capacity build, this portable option is likely not for you. However, for a lightweight, travel-friendly gaming rig, it offers a unique solution. Ensure all components are measured precisely to avoid installation issues.
Check before you buy
- Verify GPU length is under 305mm and height under 55mm.
- Confirm motherboard supports PCIe Gen 3 for the riser cable.
- Check CPU cooler height does not exceed 60mm.
- Ensure you have an SFX or SFX-L power supply.
