INTER-TECH expansion bracket for Mini ITX-601 to ITX-602 (model 88885383)

INTER-TECH expansion bracket for Mini ITX-601 to ITX-602 (model 88885383) is a hardware accessory that enables physical adaptation between two Mini‑ITX form factors. It provides a mounting interface to align mounting holes and I/O positions when converting or upgrading a small-form-factor system from the 601 layout to the 602 layout. The bracket is intended for use inside compact PC chassis and serves as a mechanical adapter to secure the motherboard and maintain correct port access and clearance.

Advantages

The expansion bracket offers a straightforward mechanical solution to address incompatibilities between Mini‑ITX-601 and ITX-602 layouts without modifying the chassis or motherboard. It simplifies installation by providing predefined mounting points and maintaining proper alignment for rear I/O connectors. The accessory is compact, made for internal installation, and reduces the need for custom fabrication or improvised mounting methods.

Suitable for

• System builders converting a Mini‑ITX-601 chassis to accommodate an ITX-602 motherboard
• Technicians performing upgrades or component rearrangements in compact desktop or embedded systems
• Repair shops needing a repeatable mounting solution for small-form-factor refurbishments

Key specifications

• Form factor compatibility: adapts Mini‑ITX-601 layout to ITX-602 layout
• Material: metal construction designed for internal chassis mounting
• Finish: corrosion-resistant surface treatment for long-term mechanical stability
• Dimensions: compact profile compatible with Mini‑ITX chassis (check physical clearances before installation)
• Mounting: includes predefined screw hole pattern for motherboard and chassis alignment

How to use

Install the bracket inside the chassis by aligning its mounting holes with the case standoffs or designated attachment points. Secure the bracket to the chassis using appropriate screws, then mount the ITX-602 motherboard onto the bracket aligning the board’s holes with the bracket’s screw pattern. Verify that rear I/O ports align with the chassis cutout and that there is sufficient clearance for cables and cooling components before finalizing screw torque. Follow standard ESD precautions and power down the system prior to installation.

Usage recommendations

Before installation, compare the physical dimensions and rear I/O positions of your chassis and motherboard to ensure compatibility. Use manufacturer-recommended mounting hardware and avoid overtightening screws. If additional clearance is needed for cooling or cable routing, plan component arrangement accordingly.
