Mount Pro Blue Aluminium mount by OWC, model OWCMMP35T25, aluminium construction, blue finish

OWC Mount Pro Blue Aluminium is a lightweight aluminium mounting bracket engineered to hold a 2.5" hard drive or SSD in place of a 3.5" drive tray in compatible Apple Mac Pro tower models. The bracket’s open, powder-coated aluminium construction in blue improves heat dissipation and provides a clear visual indication of bays populated with 2.5" form-factor drives. It is intended for users who need a simple, secure way to install any 2.5" HDD or SSD into supported Mac Pro systems (2009 and later Nehalem and Westmere tower generations) while maintaining correct SATA alignment to the backplane.

Advantages

The aluminium construction keeps weight to a minimum while offering corrosion resistance and durable mechanical support for 2.5" storage devices. The open design promotes airflow around the drive, aiding heat transfer from the drive surface to the case environment. The blue finish provides quick visual identification of modified bays and a powder-coated surface that resists scratches and surface wear. Installation requires only basic tools and the included mounting screws, making the bracket suitable for both home and professional environments.

Suitable for

• Adding any 2.5" HDD or SSD to compatible Apple Mac Pro tower systems (Nehalem & Westmere generations, 2009 and later)
• Upgrading storage in home, studio, or small professional server setups
• Situations where improved airflow and lightweight mounting brackets are preferred

Key specifications

• Material: Powder-coated aluminium for lightweight strength and corrosion resistance
• Finish: Blue powder coat for visual identification and surface protection
• Compatible drive form factor: 2.5" HDD and 2.5" SSD
• Compatibility: Designed to align 2.5" drives with Mac Pro tower SATA backplane on supported models (Nehalem & Westmere generations)
• Mounting: Attaches to standard 3.5" drive tray space using four included mounting screws
• Design: Open-frame layout to facilitate heat dissipation from mounted drives

How to use

Attach your 2.5" hard drive or SSD to the bracket using the four supplied mounting screws so the drive’s SATA connector faces the bracket’s rear. Remove the existing 3.5" drive tray from the Mac Pro and replace it with the Mount Pro 2.5 assembly, ensuring the bracket is seated so the drive's SATA connector aligns with the backplane port. Reinstall any retaining hardware and power on the system to verify drive detection. No special drivers are required for standard SATA drives; follow standard disk formatting procedures within macOS or your preferred operating system.

Usage recommendations

Verify your Mac Pro model generation before installation; this bracket is not suitable for 2006–2008 Mac Pro units. For best thermal performance, avoid enclosing the bracket in additional insulating material and ensure internal case airflow is functioning. Use the included mounting screws and confirm the SATA connector is fully seated to prevent connectivity issues. Retain the original drive tray hardware in case you need to revert to the previous configuration.
