SGPC 5L vs 8.3L Case Specs
Case Volume
The SGPC 5L Portable Mini-ITX Case offers a tight 5.1-liter internal volume. This layout fits small desks and backpack-friendly setups for builders who want a real small form factor PC. The SGPC 8.3L Portable Mini-ITX Case provides 8.3 liters of space. Its larger dimensions allow for more internal flexibility. You get extra room for components without sacrificing portability. The 8.3L model measures 151 x 306 x 179 mm. The 5L model is significantly more compact. If your priority is minimal footprint, the 5L wins. If you need more breathing room, the 8.3L is better.
GPU Compatibility
Graphics card support differs significantly between these two chassis. The SGPC 5L supports GPUs up to 185mm in length and 43mm in thickness. This limits you to shorter, thinner cards unless you use a specific riser. The SGPC 8.3L supports much larger cards, up to 300mm in length and 60mm in height. It also allows for a 27mm shoulder height. Both require an additional dual reverse connector riser cable for installation. The 8.3L accommodates a wider range of modern graphics cards. The 5L restricts you to very compact options.
Motherboard Support
Both cases are designed for Mini-ITX motherboards. The SGPC 5L explicitly supports standard Mini-ITX boards. The SGPC 8.3L supports standard ITX motherboards with a maximum size of 170x170mm. This covers the standard Mini-ITX footprint. Neither case supports larger form factors like Micro-ATX or ATX. The motherboard support is effectively identical for your typical Mini-ITX build. You can use the same mainboard in either chassis without compatibility issues. The difference lies in how the board fits within the larger volume of the 8.3L model versus the snug fit in the 5L.
Power Supply
Power supply options vary between the two models. The SGPC 5L is built for Flex-1U power supplies. This is a specific, compact form factor that saves space but may be harder to find. The SGPC 8.3L supports standard SFX PSUs with a maximum size of 125x100x64mm. It explicitly notes that SFX-L PSUs are not compatible. Standard SFX units are generally more common and easier to source than Flex-1U units. This gives the 8.3L a practical advantage for builders looking for readily available power solutions.
Cooling Design
Thermal management relies on different approaches. The SGPC 5L uses vented steel panels to help airflow in a dense layout. It does not list specific CPU cooler height limits. The SGPC 8.3L features excellent thermal performance with highly ventilated side panels. It supports CPU air coolers up to 69mm in height. The 8.3L can deliver exceptional cooling efficiency even without installing case fans. The 5L relies more on its vented steel construction for passive airflow. The 8.3L offers more explicit cooling headroom for air coolers.
Storage Options
Internal storage capacity is limited in both cases. The SGPC 5L includes two 2.5-inch SSD or HDD bays with anti-vibration mounts. This allows for stable expandable storage for two drives. The SGPC 8.3L supports the installation of only one 2.5-inch SSD or HDD. If you need to store multiple drives internally, the 5L provides double the capacity. The 8.3L sacrifices storage slots for its larger internal volume and GPU clearance. You will need external storage or M.2 drives if you choose the 8.3L.
Side Panel Material
The side panel construction differs in material and quantity. The SGPC 5L features 1.5mm steel construction with ventilated side panels. It uses a single steel panel design. The SGPC 8.3L is made of 1.5mm SPCC steel but includes an extra 3mm acrylic ventilated side panel in addition to the two original SPCC panels. This gives you more options for airflow or aesthetics. The 8.3L offers a hybrid steel and acrylic approach. The 5L sticks to a pure steel ventilated design.
