Built for Rendering and AI Workloads

This workstation pairs a 24-core Intel Core Ultra 9 285K with 192GB DDR5 and an Nvidia GeForce RTX 5090 32GB. The Samsung 990 PRO 4TB NVMe drive and Z890 motherboard provide fast storage and connectivity. It targets professionals running local AI models, complex 3D rendering or multi-layer video editing who need high memory capacity and GPU compute in a single mid-tower system.

Pre-Assembled Liquid-Cooled Platform

The PC arrives fully built with a 360mm AIO cooler mounted on the LGA 1851 socket and a 1200W 80 PLUS Gold PSU installed. All four memory slots are populated to reach the 192GB maximum, leaving no room for RAM upgrades without replacing modules. The Ceres 300 case includes front and rear 140mm fans, but internal cable routing around the large GPU and radiator can restrict access to M.2 slots or SATA ports for later storage additions.

PCIe 4.0 Storage and Connectivity Ceiling

The 4TB Samsung 990 PRO operates at PCIe 4.0 x4 speeds with sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec. The Z890 board provides four M.2 connectors and four SATA 6Gb/s ports, yet the CPU and chipset lane budget caps total simultaneous high-speed devices. Networking tops out at 2.5Gbps Ethernet and Wi-Fi 7 2x2, while rear I/O includes Thunderbolt 4 and multiple 20Gbps and 10Gbps USB ports.
