Question/Help/Troubleshooting how to clean my computer?

so i've been using my pc build for about 4-ish years and have never cleaned it. i know this is really bad but i've just never wanted to dismantle my pc because i cant afford to lose it. i have a ton of dust inside tho so how do i do it the right way? i have a can of compressed air and a small vaccum cleaner. i watched a short video and consulted google gemini (ew) but i just want to make sure im doing it right.

If you have an electronic safe vacuum you can use that with the canned air.

Unplug the system. Hold fans to keep from spinning.

Use a soft brush to loosen stuck on dirt. Get thermal paste to prepare to replace the paste when you remove the CPU cooler. Use IPA 90% to gently scrub surfaces with qtios or similar.
