Tower to rack conversion kit Thermaltake AC-078-ON1NAN-A1 for Mini Tower chassis, black, 145×266×459 mm

Thermaltake AC-078-ON1NAN-A1 is a tower-to-rack conversion kit designed for Mini Tower chassis such as The Tower 250. Finished in black, this single-piece kit provides a bottom cover panel and a display stand that enable horizontal or rack placement of a Mini Tower case. The kit measures 145 × 266 × 459 mm overall and supplies stable support and dust protection for horizontal display or rack-mounted use.

Advantages

The conversion kit allows a Mini Tower chassis to be positioned horizontally without modifying the original case, offering an alternative viewing orientation and easier access for customization. A bottom cover panel with an attached dust filter protects internal components from debris when the case is placed horizontally. Anti-scratch rubber pads protect the chassis finish during installation while an anti-slip design secures the chassis on the stand for stable placement.

Suitable for

• Horizontally displaying a Mini Tower case such as The Tower 250
• Rack or shelf placement where horizontal orientation is required
• Users who want easier access for internal customization and cable management
• Environments requiring additional dust protection while the chassis is horizontal

How to use

Remove the original feet from the base of the Mini Tower chassis, position and install the display stand in place, then attach the supplied bottom cover panel with its dust filter. Carefully place the chassis onto the display stand, making sure the rubber pads align to avoid contact scratches. Ensure the case sits securely on the elevated stand and confirm the anti-slip features engage before leaving the system unattended.

Recommendations

Place the conversion kit on a level, stable surface and avoid exposing the chassis to direct airflow that can overload the dust filter. Periodically remove and clean the dust filter according to the case manufacturer’s guidance. When mounting in a rack or confined space, verify sufficient ventilation and clearance for connectors and cables.
