Volume, Cooling, and Build Specs
Case Volume
The SGPC 4.1L Mini-ITX Case offers a tight 4.1-liter footprint, measuring 8.9 inches in length, 3 inches in width, and 9.8 inches in height. This compact design suits small desks or home theater setups where space is limited. In contrast, the SGPC 8.3L Portable Mini-ITX Case provides 8.3 liters of volume, with dimensions of 12 inches in length, 5.94 inches in width, and 7.05 inches in height. The larger interior allows for more flexible component placement and better airflow potential. If your priority is minimizing desk footprint, the 4.1L model wins. If you need extra room for cables and larger components, the 8.3L model is the better choice.
Cooling Support
Thermal management differs significantly between these two chassis. The SGPC 4.1L Mini-ITX Case supports CPU air coolers up to 56mm in height. This restriction limits you to low-profile coolers, which are necessary for maintaining its ultra-compact profile. The SGPC 8.3L Portable Mini-ITX Case supports taller CPU air coolers, reaching up to 69mm in height. This additional clearance allows for more robust cooling solutions, which can help maintain stable performance under load. The 8.3L case also features a highly ventilated side panel to aid airflow. For users planning to use standard or larger air coolers, the 8.3L model provides a clear advantage.
GPU Compatibility
Graphics card support is a major differentiator. The SGPC 8.3L Portable Mini-ITX Case supports GPUs up to 300mm (11.81 inches) in length. It also allows a GPU shoulder height of 27mm, though you must purchase an additional 18.5cm dual reverse connector riser cable separately. The product data for the SGPC 4.1L Mini-ITX Case does not list specific GPU length or height limits. Given its much smaller 4.1-liter volume, it likely accommodates only very short, low-profile cards. If you intend to install a standard-sized discrete graphics card, the 8.3L case is the only viable option among the two.
Portability
Moving your PC between locations requires different considerations for each case. The SGPC 8.3L Portable Mini-ITX Case is designed for transport, featuring two carrying handles: one plastic handle and one PU leather handle. This design allows you to easily move the chassis or fit it into a backpack. The SGPC 4.1L Mini-ITX Case weighs 4.21 pounds, while the 8.3L model weighs 7.28 pounds. The 4.1L case lacks mentioned carrying handles. For users who need to frequently transport their build, the dedicated handles on the 8.3L model make it significantly more convenient.
Power Supply Support
Internal power supply options vary by case size. The SGPC 8.3L Portable Mini-ITX Case supports SFX power supplies with a maximum size of 125x100x64mm. It explicitly notes that SFX-L PSUs are not compatible. The SGPC 4.1L Mini-ITX Case supports Flex-1U power supplies, which are smaller and typically used in HTPC or office builds. Flex-1U units are generally less powerful but fit into tighter spaces. If you need a standard SFX PSU for better wattage options, the 8.3L case is the choice. If you prefer the ultra-compact Flex-1U form factor, the 4.1L case is suitable.
Which SGPC Mini-ITX Case Fits You
HTPC and office users with tight desk space
Choose the 4.1L case if your priority is a minimal footprint for small desks or home theater setups. Its 4.1-liter volume and 3-inch width fit tightly in constrained areas. It supports low-profile CPU coolers up to 56mm and includes front USB and Type-C access for easy peripheral connectivity in office or media environments.
Portable builders who need to move their PC
Select the 8.3L case if you need to transport your build frequently. It features two carrying handles, including a PU leather option, for easy mobility. The 8.3-liter volume provides more internal space while remaining compact enough to fit into a backpack, making it ideal for users who switch locations often.
Users building with standard SFX power supplies
The 8.3L case supports standard SFX power supplies with a maximum size of 125x100x64mm, offering flexibility for standard small form factor builds. It also accommodates GPUs up to 300mm in length. Note that you must purchase a riser cable separately, as it is not included with this chassis.
Builds requiring higher CPU cooler clearance
If you plan to use a taller air cooler, the 8.3L case supports CPU coolers up to 69mm in height. This extra clearance, combined with its ventilated side panels, ensures better thermal performance for more demanding components compared to the 4.1L case, which limits coolers to 56mm.
