It supports motherboards from ITX up to E-ATX, making it suitable for a wide range of builds from budget gaming rigs to high-end workstations. Positioned in the mid-range segment, the MasterBox 600 Lite stands out by offering premium features like back-connect motherboard compatibility and 420mm radiator support at a very competitive price point. It's an excellent choice for builders who want a clean, cable-free interior without breaking the bank.

Compatibility Guide

The MasterBox 600 Lite supports ITX, Micro ATX, ATX, and back-connect ATX motherboards. E-ATX boards up to 12" x 10.9" (30.5cm x 27.7cm) can also be installed, though some cable management features may be limited in that configuration. Power supply mounting is bottom-mounted, with a maximum length of 170mm (with HDD cage) or 210mm (without HDD cage). Graphics card clearance is 360mm with a front radiator installed, or 410mm without. CPU cooler height clearance is 170mm.

Product Info

Released in early 2024, the MasterBox 600 Lite carries a street price around ¥10,000 (approximately $70 USD), offering exceptional value for its feature set. It comes with a 2-year warranty. Market positioning is mid-range, but the inclusion of back-connect motherboard support and 420mm radiator compatibility pushes it into premium territory. It's a well-balanced case that can serve both entry-level and high-end builds effectively.

Best Use Cases

Builders wanting a clean, cable-free look with back-connect motherboards: If you're using an ASUS BTF, MSI Project Zero, or GIGABYTE Project Stealth motherboard, this case is optimized to hide almost all cables, resulting in a stunningly clean interior. Gamers installing large, high-end GPUs: With up to 410mm of GPU clearance, even the largest RTX 4090 cards fit easily. The triple 140mm front fans provide strong airflow to keep components cool under load. Enthusiasts planning a custom water-cooling loop: The front supports radiators up to 420mm, and the top can accommodate a 360mm radiator, giving plenty of room for extensive liquid cooling setups. Budget-conscious builders who don't want to compromise on expandability: At around ¥10,000, this case offers E-ATX support, multiple storage bays, and excellent airflow, making it a great choice for those who want maximum flexibility without spending a lot.

Things to Consider

If you're not using a back-connect motherboard, the MasterBox 600 Lite still works perfectly with standard ATX boards, but you won't benefit from the cable-hiding design. In that case, other cases at a similar price point might offer better value. When installing an E-ATX motherboard, be aware that some cable routing grommets may be blocked, and the included cable management space might be tighter. Also, there are no 5.25-inch drive bays, so optical drives or fan controllers will need external solutions. The stock 140mm fans are 3-pin DC-controlled, not PWM. While they are quiet and move decent air, enthusiasts who prefer PWM control for precise speed regulation may want to replace them. ## FAQ
Q: Can I install an ASUS ROG STRIX B760-F GAMING WIFI motherboard in this case? A: Yes, any standard ATX motherboard will fit without issues. The case fully supports non-back-connect ATX boards as well. Q: Will a 360mm radiator fit in the front? A: Absolutely. The front supports radiators up to 420mm, so a 360mm radiator fits easily. Just ensure your GPU length doesn't exceed 360mm if you mount the radiator in the front. Q: Are the included fans PWM? A: No, they are 3-pin DC fans. You can control their speed via DC voltage control on your motherboard, but if you need PWM functionality, you'll need to purchase aftermarket fans.
