Parts list: https://pcpartpicker.com/list/2GWhpK

First computer built from the ground up. I need to replace my Windows 10 laptop that couldn't be upgraded to Windows 11. Purpose: Watch 4K UHD BluRays and local LLM training.

Goals

• Reuse old chassis in the house. Which means it would be a sleeper build.

• Buy used, if available and in good condition

• Watch 4K UHD BluRay

• Train LLMs locally

• Use a Linux OS (Ubuntu 24.04 LTS)

Notes

Since I'm not good at drilling, the biggest challenge is ensuring good airflow from the stock chassis. The CPU Cooler is meant to be a Noctua NH-D15. Learned too late that the radiator wouldn't fit; the PSU is in the way. Fortunately, the included NF-A15s could be repurposed as chassis fans, thanks to some cable ties that come with the PSU. One is placed in the side, the other in the front near where the original speaker used to be. These are intake fans.

Outtake fans are two blowers that fit in PCI expansion slots. Some slots are effectively blocked by the M2 slot heat sinks.

The built-in WiFi board has no Linux driver. A USB dongle had to be used instead.

Motherboard is chosen to eventually accommodate an RTX5090, if needed.
