The 360mm AIO liquid cooler helps top this all off by providing superior thermal performance. Grab it now for a huge $688 off while this offer lasts!

On paper, this should behave like the sort of system that brute-forces almost any mainstream gaming workload you throw at it. The 9800X3D is tuned toward top-tier game performance, the RTX 5090 is the most powerful GeForce card in NVIDIA’s current stack, and 64GB of DDR5 removes a common memory ceiling that can appear in more compromised prebuilts. The use of a 360mm liquid cooler and a 1000W PSU suggests the build is designed to sustain that hardware properly rather than just list it. As a result, the X6 ONAMI reads as a serious 4K enthusiast tower with enough compute overhead to handle demanding productivity and AI-accelerated workloads alongside gaming.
What we like about this Xidax X6 ONAMI BLACK Gaming PC
RTX 5090 and Ryzen 7 9800X3D creates an unapologetically enthusiast-grade gaming build
The headline pairing here is NVIDIA’s GeForce RTX 5090 with 32GB of GDDR7 and AMD’s Ryzen 7 9800X3D. That immediately places the system in flagship territory for gaming. The RTX 5090 is NVIDIA’s top GeForce-class Blackwell card and is positioned for the most demanding gaming and creator workloads, while the 9800X3D remains one of the most gaming-optimised desktop CPUs thanks to its large low-latency cache design. This is not a general-purpose balanced build trying to do a bit of everything; it is clearly aimed at users who want a system built for elite gaming performance first, with creator capability following naturally from the sheer hardware level.

64GB DDR5-6000 gives it unusually strong headroom for multitasking and creation
A lot of high-end prebuilts still stop at 32GB, but Xidax pushes this configuration to 64GB of DDR5-6000. That is a meaningful technical advantage for users who multitask heavily, run memory-hungry games with background apps open, work in large image or video projects, or simply want a system that will stay comfortable for years. At RTX 5090 level, that kind of memory capacity also makes the machine feel more complete, because it better matches the GPU’s role in creator software, AI workloads, and high-end desktop use beyond gaming.
Cooling and chassis design are scaled for the component class
The X6 ONAMI uses a 360mm AIO and a 1000W PSU in a glass-heavy ONAMI chassis, with Xidax also highlighting upgradeability and stress testing before shipping. Those are the right kinds of engineering choices for a machine at this level. A flagship GPU and high-performance X3D processor need proper thermal and power support, and a 360mm liquid cooler is a better match for the ambitions of the system than a smaller air-cooling setup would be. The chassis itself also appears designed to present the build visually, which matters for buyers spending in this part of the market.
The support model adds real value to a premium prebuilt
Xidax includes lifetime service and labour support, along with pre-shipping stress testing, thermal checks, BIOS checks, and a clean Windows install with only the necessary drivers. That matters more than it might on a lower-cost system, because buyers at this price point are paying for convenience and confidence as much as for the parts list. Good support and validation reduce the friction that can otherwise undermine the appeal of a very expensive prebuilt.
Who is this RTX 5090 PC deal suitable for?
This PC is for buyers who want an ultra-premium gaming desktop and are happy to lean fully into enthusiast-class hardware. It is especially well suited to 4K high-refresh gaming, heavy multitasking, and creator workflows that can benefit from a 32GB flagship GPU and 64GB of system memory.
