SGPC K39 5L vs K49 7.1L Comparison

Case Volume

Edge: SGPC K49 7.1L Portable Mini-ITX Case

The SGPC K39 5L Portable Mini-ITX Case offers a compact 5.1L internal volume. This tight layout fits small desks and backpack-friendly setups for builders who want a real small form factor PC. In contrast, the SGPC K49 7.1L Portable Mini-ITX Case provides a larger 7.1L volume. This extra space accommodates bigger components and improves airflow potential. The K49 measures 130 x 304 x 179 mm, while the K39 is smaller at 4.7 x 8.7 x 7.7 inches. You should choose the K39 if portability is your top priority. Choose the K49 if you need more room for components and cooling.

GPU Compatibility

Edge: SGPC K49 7.1L Portable Mini-ITX Case

Graphics card support differs significantly between these two cases. The SGPC K39 5L Portable Mini-ITX Case supports GPUs up to 185mm in length and 43mm in thickness when used with a compatible dual reverse riser cable. This limits you to short, low-profile cards. The SGPC K49 7.1L Portable Mini-ITX Case supports much larger GPUs up to 300mm in length and 45mm in height. The K49 also specifies a shoulder height limit of 27mm. Both require a separate riser cable. If you plan to use a standard-sized or larger graphics card, the K49 is the clear choice. The K39 is strictly for very short cards only.

Power Supply Type

Edge: SGPC K49 7.1L Portable Mini-ITX Case

The power supply requirements are a major differentiator. The SGPC K39 5L Portable Mini-ITX Case is built for Flex-1U power supplies. This specialized form factor saves space but can be harder to find and often costs more. The SGPC K49 7.1L Portable Mini-ITX Case supports standard SFX PSUs with a maximum size of 125x100x64mm. SFX-L PSUs are not compatible with the K49. Standard SFX units are generally more common and easier to source than Flex-1U options. This makes the K49 more practical for most builders. You will have fewer compatibility headaches with the K49 due to the standard PSU support.

Storage Options

Edge: SGPC 5L Portable Mini-ITX Case

Internal storage capacity varies between the two models. The SGPC K39 5L Portable Mini-ITX Case includes two 2.5-inch SSD or HDD bays. These bays feature anti-vibration mounts to ensure stable operation for your drives. This allows for more flexible storage configurations. The SGPC K49 7.1L Portable Mini-ITX Case supports only one 2.5-inch SSD or HDD. If you need to install multiple storage drives, the K39 provides the necessary space and mounting points. The K49 limits you to a single drive. For builders who prioritize storage expandability, the K39 is the better option. The extra bay in the K39 is a practical advantage.

Side Panel Material

Edge: SGPC K49 7.1L Portable Mini-ITX Case

Both cases use 1.5mm steel for their primary structure, but the side panels differ. The SGPC K39 5L Portable Mini-ITX Case features vented steel panels. This maintains a uniform material look and provides airflow. The SGPC K49 7.1L Portable Mini-ITX Case includes two original SPCC steel side panels but also comes with an extra 3mm acrylic ventilated side panel. This gives you a material choice between steel and acrylic. The acrylic option offers a different aesthetic while still providing ventilation. The K49 provides more versatility in side panel materials. You can choose the look that best fits your build style with the K49.

Weight

Edge: SGPC 5L Portable Mini-ITX Case

Portability is affected by the weight of each chassis. The SGPC K39 5L Portable Mini-ITX Case weighs 4.14 pounds. This lighter weight makes it easier to carry in a backpack or move around frequently. The SGPC K49 7.1L Portable Mini-ITX Case weighs 5.45 pounds. The additional weight comes from the larger volume and the inclusion of an extra side panel. The K49 also includes two carrying handles, one plastic and one PU leather. While the K49 is heavier, the handles mitigate the inconvenience. The K39 remains the lighter option for pure portability. Choose the K39 if minimizing weight is critical for your transport needs.
