Viking Six | NVIDIA RTX 5080 16GB + Ryzen 7 9800X3D | Ready-to-Go Gaming PC | PC36

🌲 Viking Six

Flagship interior; Scandinavian exterior.

Viking Six is the system that proves the entire point of the Viking series. The 9800X3D sits at the top tier of gaming CPU performance. The RTX 5080 breezes through 4K ultra in modern AAA titles with comfortable ray tracing headroom. The SFX power supply gives the GPU the clearance it deserves - With a powerful yet beautifully simple optimised air cooling setup for maximum reliability.

All of this sits inside the same walnut-fronted mATX case that opens the series, looking entirely at home in a living room, study, or anywhere else a glowing tower would feel out of place. This is what flagship looks like when you remove every assumption that power has to announce itself. 

We designed the Viking series for those who value flagship performance, but in an attractive, grown-up package that doesn't scream "gamer."

🧬 Built to last, designed to evolve

This system is built on AMD's latest AM5 platform, which offers one of the best upgrade paths available today. That means you can start with a great processor now and still have room to move up the stack later, while keeping the same motherboard, case, power supply and most of your core components. GPU, storage and cooling are all easily upgradable so the system can grow with your needs over time.

👁️ Transparency notes

• Photos and graphics are representative — the build you receive will match the spec listed here. Some visual details (component branding, exact fan models, etc.) may vary depending on stock availability at the time of build, but performance and quality remain consistent across all units.
• Some components (RAM brand, NVMe brand, motherboard model within the chipset and VRM specification) may vary based on supplier availability at the time of build. We only use components that meet our specification and trusted brand criteria — see our Trusted brands page for the full list.
• Glass panel note: Photos may show a tempered glass side panel — this is an optional upgrade. The standard Viking Six configuration ships with the mesh side panel, which complements the walnut front for a clean, understated look without showing off the internals. A glass panel is available as a quick-add upgrade on the listing options if you prefer the showcase look.

🛠️ Popular upgrade options
