The Phanteks NV7 full tower houses the entire system — Phanteks case, Phanteks Glacier One 360 D30 X2 AIO, and nine Phanteks D30 fans — in a completely unified D-RGB ecosystem that requires a single cable connection for all lighting and fan control. The Summit 285K Intel Core Ultra 9 285K RTX 5090 gaming PC is a system without compromise, built for buyers who want the absolute best available.

4TB PCIe Gen 5 NVMe Storage

The 4TB Crucial T700 is a PCIe Generation 5 NVMe SSD, delivering sequential read speeds of up to 12,400MB/s and write speeds of up to 11,800MB/s — making it the fastest consumer storage available and approximately 70% faster than the top-tier PCIe Gen 4 drives used in other systems in this range. Built on Micron’s own 3D NAND, the T700 operates over a PCIe 5.0 x4 interface connected directly to the CPU, ensuring it operates at full rated speed at all times. 4TB of capacity provides extensive space for a large game library, creative project files, and applications simultaneously. The drive is backed by Crucial’s 5-year warranty with 2,400TB TBW endurance.

NVIDIA GeForce RTX 5090 — The Most Powerful Consumer GPU Available

The Gigabyte AORUS GeForce RTX 5090 MASTER ICE is the undisputed flagship of NVIDIA’s Blackwell generation with 21,760 CUDA cores and 32GB of GDDR7 memory across a 512-bit interface delivering approximately 1,792GB/s of memory bandwidth — nearly double the RTX 5080’s bandwidth. The AORUS MASTER ICE boosts to 2,655MHz with WINDFORCE triple-fan cooling using Gigabyte’s Hawk fan and server-grade thermal compound, sustaining higher clocks under load than the reference specification alone suggests. At 4K it renders all current titles at maximum settings with exceptional frame rates, and with DLSS 4 Multi Frame Generation generating up to three additional AI frames for every rendered frame, the effective frame rate ceiling is dramatically higher than any previous GPU generation. At 8K with DLSS 4 upscaling the Summit 285K delivers a gaming experience previously reserved for multi-GPU configurations. Fifth-generation RT cores and a 575W TBP are handled comfortably by the 1200W Lian Li Platinum PSU. Display output covers three DisplayPort 2.1b and one HDMI 2.1b for up to four monitors simultaneously.

Phanteks NV7 — Unified Full-Tower Ecosystem

The Phanteks NV7 White is a statement full-tower chassis with near-seamless tempered glass panels on the front and side providing an unobstructed view of the entire build. The NV7’s unique design places the motherboard at the centre of the build, surrounded by a strong outer frame that captures and directs attention to the internal components. The Phanteks Glacier One 360 D30 X2 White AIO tops the system — its three interconnected D30 fans simplify cable management to a single cable while the brushed aluminium pump head delivers an integrated fan that actively cools the 285K’s surrounding VRMs and M.2 SSD below it. Four Phanteks D30 Reverse Airflow D-RGB fans on the side panel direct intake airflow straight onto the RTX 5090, and two further D30 fans at the rear complete the airflow circuit. All nine fans and the AIO connect through the NV7’s onboard two-channel D-RGB controller. The NV7’s clean rear door and moveable front IO module allow the system to be placed freely without the traditionally messy rear panel visible. GPU clearance extends to 450mm.

Dual USB4, Wi-Fi 7, and Z890 Elite Connectivity

The Gigabyte Z890 AORUS ELITE WIFI7 ICE provides a feature-rich Z890 platform with dual USB4 Type-C ports running at 40Gbps with DisplayPort Alt Mode on the rear I/O, built-in Wi-Fi 7 with tri-band support across 2.4GHz, 5GHz, and 6GHz frequencies, Bluetooth 5.4, and a Realtek 2.5GbE wired LAN port. The Realtek ALC1220 codec delivers 7.1 surround sound with optical S/PDIF output. The Z890 chipset supports full CPU overclocking — unlocking the 285K’s multiplier for performance beyond its stock specification — and the primary M.2 slot operates at PCIe 5.0 x4, running the Crucial T700 at its full 12,400MB/s. The Lian Li SX Platinum 1200W provides 80+ Platinum-rated, fully modular power delivery with fanless operation up to 480W load, supported by a 10-year warranty.
