Here's some general thoughts in no particular order:
-
PC Part Picker is your friend for compatibility and sorting through all the options.
-
I have a Fractal North XL. It's a solid case. If you don't need a top of the line GPU, the regular North will do just fine.
-
Add some head room for your power supply. Get a gold or better rated one from a reputable brand.
-
Try to buy in-person from a Microcenter if you can. I brought a tablet with my list and they actually recommended some better in-house deals after reviewing my build concept. I saved money and ended up getting some backup parts.
-
From what I understand right now is that AMD is a better choice than Intel for CPUs.
-
Having one SSD as your primary drive and a secondary drive for data storage can be useful, especially if you need to reinstall the OS.
-
If you want to get into video/photo editing you'll want to consider getting more memory/RAM.
-
Take pictures while you build. Have some small containers ready for all the screws you'll be managing.
-
Build with a friend that has done this before if you can.
-
Jays2Cents has a lot of good consumer-focused videos without going too far into the technicals like GamersNexus.
-
You may find an entry level GPU useful for basic photo and video editing, but I'd read up on what's available on Linux and what's really needed.
Happy to help! Oh one more thing: Microcenter price matches, so look at competing sites the day before you go.
