Ready-to-Game Desktop

The HAJAAN PhantomX ships as a complete mid-tower system with an Intel Core i7-12700K processor, GeForce RTX 5070 graphics card with 12 GB GDDR7 memory, 32 GB DDR4 RAM, and a 1 TB NVMe SSD. Windows 11 Pro is pre-installed, and a wired RGB keyboard and mouse are included so the PC is ready for gaming, streaming, and content creation immediately after unboxing.

Liquid-Cooled Upgrade Path

This build replaces an older air-cooled desktop that struggles with modern titles at high settings or drops frames during heavy multitasking. The jump is worth it when your current CPU hits thermal limits, your GPU lacks 12 GB of video memory for texture-heavy games, or your storage loads levels noticeably slower than an NVMe drive. Buyers who need more than 1 TB of fast storage or who plan to run multiple high-refresh monitors should verify expansion options before ordering.

Standard Assembly, Watch the Coolant

The system arrives fully assembled; only the power cord, peripherals, and network connection are required to start. The closed-loop liquid cooler is pre-filled and mounted, so there is no reservoir to fill or tubing to route. The most common issue is air bubbles trapped in the radiator after transit — running the fans at maximum for a few minutes usually purges them. Ensure the tempered-glass side panel is seated evenly to avoid airflow gaps that can raise internal temperatures.

Questions about this item

What case clearance and power connectors does the RTX 5070 12 GB card require inside the mid-tower chassis?

The mid-tower case uses a liquid-cooling layout; the graphics card occupies a standard PCIe slot and draws power from the internal PSU cables already routed by the builder.

Which steps are required to add more DDR4 memory after unboxing the PhantomX?

Power off the PC, remove the tempered-glass side panel, align each DDR4 module with the motherboard slots until the retention clips click, then replace the panel and boot.

Which components are most likely to need replacement after several years of heavy gaming use?

The liquid-cooling pump, the PSU, and the 1 TB NVMe SSD are the parts that typically wear out first under sustained high-load gaming sessions.
