Questions about this item

How do I verify the liquid cooler is running after first boot?

Open the case side panel and confirm the 360 mm radiator fans are spinning; the pump runs silently so fan movement is the visible cue.

Which components ship inside the box and what must I provide?

The system arrives fully assembled with CPU, 64 GB DDR5, 4 TB Samsung 990 PRO SSD, RTX 5090 32 GB, 1200 W PSU, Windows 11 Pro, Wi-Fi 6 and BLUETOOTH 5.2; only a monitor, keyboard and mouse are needed separately.

Should I choose the 64 GB DDR5 configuration or the 192 GB maximum?

The 64 GB kit fills two of four slots and suits gaming and most creative workloads; select 192 GB only if you regularly run large AI models or multi-hour 8 K renders that exceed 64 GB.
