Liquid-cooled desktop with a six-core Ryzen processor, RTX 5070 Ti graphics, 64 GB DDR5 memory and a 1 TB NVMe SSD for gaming and creative workloads
This system arrives assembled with Windows 11 Pro, a 6-core Ryzen 5 9600X processor and an RTX 5070 Ti graphics card. The 64 GB DDR5 memory and 1 TB NVMe SSD give immediate headroom for modern workloads. It targets users who want a balanced workstation without building it themselves.
The Corsair 4000D chassis uses a conventional motherboard tray and a 240 mm AIO mounted to the top or front panel. Installation follows normal desktop steps: seat the GPU in the PCI Express x16 slot, connect the 850 W PSU cables and close the tempered-glass side panel. Builders unfamiliar with AIO orientation should verify pump placement before powering on.
The four DIMM slots support up to 192 GB total, so memory can be doubled later. The Samsung 990 PRO delivers 7450 MB/s reads and 6900 MB/s writes, keeping large media files responsive. Storage expansion is limited to two 3.5-inch and two 2.5-inch bays plus three remaining M.2 slots. Users needing multi-terabyte RAID arrays or more than 192 GB RAM will outgrow this platform.

Open Task Manager or a monitoring tool and run a single-threaded load; the CPU frequency should hit 5.40 GHz if the 240 mm liquid cooler is keeping thermals in check.
The box contains the complete desktop with Windows 11 Pro installed, liquid-cooled Ryzen 5 9600X, 64 GB DDR5, 1 TB Samsung 990 PRO SSD, RTX 5070 Ti 16 GB and 850 W PSU; you only add a monitor, keyboard and mouse.
The system ships with 64 GB DDR5 in two slots; if your workloads regularly exceed that, you can populate the remaining two slots up to the 192 GB limit.
