Pre-assembled: The aluminum foot pad model can also be modified into the aluminum handle model

The DUBILI comes with a pre-assembled aluminum alloy frame serving as its foundation. However, using such an elegant aluminum alloy frame solely as a handle seems like a missed opportunity. The package includes the main chassis base, screws, and rubber feet. Users can easily unscrew the four screws holding the aluminum alloy frame, reposition the original bottom frame to face upwards, secure the plastic base, attach the rubber feet, and the transformation is complete.

The aluminum alloy frame is set up as the default base in the factory setting. However, the kit also comes with a plastic base and a rubber pad, allowing for easy personal customization and replacement.
A 5mm hexagon socket screwdriver is also provided in the accessories.

Upon closer inspection of the aluminum alloy frame, it’s evident that it boasts more than just a hairline treatment. The frame also features a diamond-cut finish, enhancing its sophisticated appearance. During the process of disassembly and reassembly, the intricately laser-engraved hexagon socket screws with the iBuild branding are unmistakable. Every component of the case is secured with these distinct screws, underscoring the exceptional quality and uniqueness of the case.

The DUBILI offers a straightforward installation process. Its design, devoid of sub-compartments and featuring a bottom-mounted power supply, simplifies assembly. However, a tip for those installing a 360mm radiator: it’s advisable to first connect the motherboard to the CPU power supply before mounting the radiator. While there’s ample space at the top of the case, if you choose to mount the radiator before making the CPU power connection, it might challenge your finger agility.

There is enough space above the case, and the socket above the motherboard can be connected after installing the water-cooling radiator.

The DUBILI also comes with a straightforward L-shaped graphics card bracket. Simply place a rubber pad on the bracket’s front, then secure it at the necessary position for the graphics card, and you’re all set.
