HP Z1 Z1 G1i Black 2025
The Intel Core Ultra 9 285 24-core processor and 64GB of 5600 MHz DDR5 RAM deliver certified, pro-level compute for demanding multi-threaded tasks. Its expansive connectivity includes Thunderbolt, nine USB-A ports, and HDMI 2.1, while the 500W PSU and tool-less chassis offer a clear path for adding a dedicated GPU later. This tower is best for developers and engineers who need immediate, high-core-count CPU performance and extensive I/O without a discrete graphics card.
