Metallique Three | RTX 5090 + Ryzen 7 9800X3D | Ready-to-Go Gaming PC | PC36

🩵 Metallique Three

Flagship power, minimal footprint

Metallique Three represents the pinnacle of compact performance. Housing a Ryzen 7 9800X3D and RTX 5090 32GB in the ultra-dense Antec Performance 1M ITX chassis, it redefines what’s possible in small-form-factor computing. Every millimetre of space is tuned for airflow, power delivery and thermal balance — a workstation-grade system that fits almost anywhere, with performance that comfortably holds its own against much larger builds.

🧬 Built to last, designed to evolve

This system is built on AMD's modern AM5 platform, which offers one of the best CPU 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. In this ITX layout, Metallique Three is carefully tuned for long-term stability and sensible noise levels rather than unchecked power draw — a compact flagship that remains usable and reliable in real-world conditions.

👁️ Transparency notes

• We sometimes use generic component names or give a performance guarantee rather than specifying an exact brand. This is due to varying availability from our suppliers. Ask our support team any day you are ready to purchase and we will confirm your exact parts 😊
• Product images are representative photos of a similar spec in the same style – your PC will look similar but not identical. Our support team can help clarify anything you're unsure of.
• ITX builds like Metallique Three are thermally tested unrestricted, then shipped with a TJmax of around 80 °C and tuned curve optimiser settings. This helps keep noise and temperatures sensible in a very compact space and may lead to slightly reduced CPU performance compared to the same spec in a larger case.
• Due to the RTX 5090’s power draw and the realities of an ultra-dense ITX enclosure, a modest CPU power limit may be applied to maintain stable thermals. In real-world gaming, the performance impact is typically small, but it is something we think you should know up front.
