Converting a Power Mac G5 to an ATX-compatible Case: A Challenging yet Rewarding Project

The Power Mac G5, released in 2003, was a behemoth of a computer that showcased Apple's innovative design and engineering prowess. Its unique shape and robust construction made it a favorite among modders and enthusiasts. In this article, we'll explore the process of converting a Power Mac G5 to an ATX-compatible case, while preserving its original aesthetic appeal.

The project began with a thorough assessment of the case's internal layout and structure. To accommodate an ATX mainboard, significant modifications were required. The first step was to modify the back panel, moving the fans off-center to create space for new I/O ports. This modification allowed for better airflow and easier installation of components.

Next, we focused on converting the case for watercooling. Alphacool Cape Cora passive radiators were used, along with acrylic tubing from PlayDoh Silverstone TJ07. However, creating a custom acrylic manifold required painstaking work, involving over 3000 circles with a 3mm radius. The original fan grille was incorporated to maintain the case's distinctive look.

To adapt the case for an ATX-reverse mainboard, we designed and built a new back panel from scratch. This involved careful planning and precision engineering to ensure a seamless integration of components. The result was a sturdy and robust design that rivaled the original case's strength.

The most challenging aspect of this project was integrating the watercooling system with the ATX-reverse mainboard. We opted for a passive radiator setup, eliminating the need for fans to cool the system. This not only reduced noise levels but also increased overall efficiency.

Our goals for this project were twofold: preserve the original case's exterior appearance while accommodating modern hardware components. The outcome was a striking fusion of old and new, with the Power Mac G5's iconic design language merged seamlessly with contemporary engineering.

The end result is a testament to the creativity and determination required to undertake such an ambitious project. With its robust construction, custom watercooling system, and sleek design, this converted Power Mac G5 case stands as a true masterpiece among modding communities.
