System purpose

This Adamant Custom business desktop is a liquid-cooled workstation built around a 20-core Intel Core Ultra 7 265K processor, 64 GB of DDR5 memory, a 1 TB NVMe SSD and a 10 TB hard drive. It ships with Windows 11 Pro and an Nvidia RTX A400 graphics card offering four Mini DisplayPort outputs. The system targets professionals who need multi-threaded CPU performance, large local storage and certified drivers for creative or technical applications.

Who should consider this and who should not

The machine suits users who rely on many CPU cores, ECC-capable memory headroom up to 192 GB and quiet liquid cooling for long render or compute sessions. It is not for buyers who want more storage bays than the three 3.5-inch and three 2.5-inch internal slots provide, nor for anyone needing a graphics card with more than 4 GB of video memory or additional display connectors beyond the four Mini DisplayPort ports.

Deciding specification — GPU video memory

The RTX A400 includes 4 GB of VRAM, which determines whether the workstation can hold your working datasets, textures or frame buffers on the graphics card itself. If your workflow regularly exceeds that capacity, you will need a system with a larger-frame-buffer GPU.

Questions about this item

What PCIe generation does the RTX A400 graphics interface use, and what bandwidth does that cap in practice?

The RTX A400 connects via PCI Express x16; the board supplies PCIe 4.0 lanes so the card is limited to the 4.0 x16 ceiling.

What are the case dimensions and motherboard form factor that determine whether this system fits on a desk or in a rack?

The Antec P10 FLUX measures 477 mm deep, 220 mm wide and 486 mm high and houses an ATX motherboard.

How is the 240 mm liquid cooler installed, and which step do builders most often get wrong?

Mount the radiator with tubes at the bottom or side, not the top, to keep air out of the pump — that orientation mistake causes noise and premature failure.
