My laptop is running out of storage space and I don't have anything I can remove anymore to increase it by much, so I'm thinking about building a pc. I'd also like to find a better gpu for doing video editing.
It will be the first one I've built, so I don't really know what I need. Also, does it matter for compatibility for Linux whether I go with AMD or Intel?
The high end of what I want to use it for is video editing with Kdenlive or Davinci Resolve, some modeling and animation in Blender, and some light gaming, like Minecraft or TUNIC.
I figure one of these guides might be useful, but I don't really know which.
Is there anything else I should know for setting up a PC to run Linux?
Be safe - don't wear socks, stand on a hard floor if possible, ground yourself if you have a wrist strap for that, and discharge any static by touching metal and/or the case before touching any components. And no matter what, DO NOT open the power supply, and definitely don't touch anything in it!
The huge motherboard connector probably requires more force than comfortable.
Watch through at least one build guide before starting. That way you know the process.
Hope that helps, and don't let it scare you away - it's really fun to do and if you're careful, chances are nothing major will go wrong.
