The IPC 4U 4129L is a 4U chassis with a depth of 695 mm, providing ample space for powerful server systems. The front features two removable drive cages with integrated 120 mm fans, each accommodating up to 5x 3.5-inch hard drives that can be installed without screws. Each drive cage can easily accommodate 3x 5.25-inch hot-swap frames, allowing for easier access to the hard drives (available as an option). Additionally, five extra fans in the middle bar and at the back ensure optimal cooling for the entire system.
