As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The SGPC K49BL 8.3L Portable Mini-ITX Case offers a compact chassis with dual handles and SFX PSU support. If you are looking for sgpc k49bl 8 3l mini itx alternatives, you might want a different size or feature set. This original model limits you to standard ITX motherboards and excludes GPU riser cables. You may prefer a case with included accessories or a different power supply form factor.
The alternatives on this list were chosen because their specs overlap with the original. They all support Mini-ITX motherboards and maintain a small form factor footprint. Some options, like the SilverStone SG13B-Q, accommodate standard ATX power supplies for broader compatibility. Others, such as the Cooler Master NCORE 100 MAX, include bundled cooling and power solutions. This guide compares these cases strictly by their published specifications to help you find the right fit for your build.
Our top pick: SGPC 8.3L Portable Mini-ITX Case.
How alternatives compare to SGPC
SilverStone Small Form Factor Mini-ITX Case
The SilverStone SG13B-Q supports standard ATX power supplies instead of the smaller SFX units found in the SGPC case. This gives you more PSU options, though the chassis grows to 14 by 12 by 10 inches. You sacrifice the compact 8.3L volume and the dual carrying handles for a larger, heavier 6-pound build. It is a solid choice if you want reliable Mini-ITX compatibility without hunting for small form factor components. The trade-off is clear: you gain power supply flexibility but lose the portability and tight footprint of the original model.
SilverStone Slim Mini-ITX Case with Handle
The SilverStone ML08B-H is a slim Mini-ITX case that also accepts SFX power supplies, matching the SGPC in that regard. However, it measures 14.6 by 15 by 3.4 inches, making it significantly wider and flatter than the SGPC 8.3L. At 7.72 pounds, it is heavier and lacks the integrated dual handles of the original. You get a different form factor that might fit better in certain bags or desks. This option suits users who prefer a low-profile design over the boxy shape of the SGPC, while still maintaining SFX compatibility.
SGPC 5L Portable Mini-ITX Case
The SGPC K39 shrinks the footprint dramatically to just 5 liters, measuring 7.7 by 4.7 by 8.7 inches. It weighs only 4.14 pounds, making it far easier to carry than the 7.28-pound original. You give up the ability to use larger components and the spacious 8.3L interior. This case is best for experienced builders who need maximum portability and have already sourced low-profile parts. If your priority is moving your PC frequently and you do not need extra room for cables or large GPUs, this smaller SGPC model is the practical alternative.
HYTE Revolt 3 Mini-ITX Case with Handle
The HYTE Revolt 3 offers full side access and modern USB-C connectivity, differing from the SGPC’s specific header requirements. It measures 9.9 by 7 by 16.1 inches and weighs 11 pounds, making it much larger and heavier than the portable SGPC. You trade the compact 8.3L size and dual handles for easier maintenance and a sturdier metal chassis. This case is ideal for builders who value easy access to components and modern I/O over extreme portability. It is a stationary build solution rather than a travel-friendly option like the original.
JOYJOM 4.3L Aluminum Mini-ITX Case
The JOYJOM 4.3L Aluminum Case is significantly smaller than the SGPC, measuring 7.24 by 4.09 by 8.78 inches and weighing just 2.51 pounds. It is designed for low-profile components, which limits GPU and cooler options compared to the SGPC’s 300mm GPU support. You gain extreme portability and a lighter aluminum build but lose the ability to use standard-sized parts. This alternative is for users who prioritize a tiny footprint and light weight over component compatibility. It is a niche choice for those who need to move their PC often and have specific low-profile hardware.
Cooler Master NCORE 100 MAX Mini-ITX Case
The Cooler Master NCORE 100 MAX supports 120mm fans and comes with a bundled high-wattage PSU and liquid cooling solution. It measures 6.1 by 18.9 by 8.35 inches and weighs 13.9 pounds, making it much larger and heavier than the SGPC. You sacrifice portability and the 8.3L volume for enhanced cooling performance and included power supply. This case is for builders who want a compact Mini-ITX chassis with superior thermal capabilities and do not need to carry it. It is a stationary alternative for those who prioritize cooling and convenience over mobility.
