Questions about this item

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

Enter the BIOS and check the CPU fan header shows a stable RPM reading for the 240 mm AIO pump; the Ryzen 9 9900X3D should idle well below its 5.50 GHz boost ceiling.

Which components ship inside the Antec P20 case and what must I provide?

The tower arrives fully assembled with the PRIME X870-P motherboard, 128 GB DDR5, dual 4 TB Samsung 990 PRO SSDs, 10 TB HDD, RTX 5060 8 GB GPU, 850 W PSU and Windows 11 Pro — only a monitor, keyboard and mouse are needed.

Should I choose the 128 GB DDR5 configuration or the maximum 192 GB option?

The system ships with four populated slots at 128 GB; selecting 192 GB would require a later module swap, so stay with 128 GB unless your workloads consistently exceed that capacity.
