Reddit mentions of CORSAIR CRYSTAL 280X RGB Micro-ATX Case, 2 RGB Fans, Lighting Node PRO included, Tempered Glass - Black (CC-9011135-WW)

This case has two chambers. It's just housed on the back side where you can't see it instead of the bottom. So it's wider instead of taller.

You could get something like this very nice mATX case with LL120 RGB fans (objectively some of the prettiest RGB fans around:

Though this would cost you most of the budget, and RAM/CPU cooler would surpass the budget. Also note it's a pretty wide case, due to the dual chamber design. It does come with a Lighting Node Pro, for software control, which can also be expanded with the LED expansion kit LED strips later: https://www.amazon.co.uk/Corsair-CL-8930002-RGB-Lighting-Expansion/dp/B073VKPM4D

I bet it looks great.I am secretly happier with the keyrings than the actual pickaxe lol.i would of put the normal size funko pops in there but my build is a Micro-ATX so the normal size ones look a little bit big inside my case

Likely because they're out of production, and when supply dwindles they go massively up in price since if there's someone looking for that specific case brand new, they'll pay the inflated price. But unless you find that person, it's definitely not worth $200.

Current equivalent is the 280X, more expensive since it's RGB and Glass, but basically the modern 240.

This is the case. Comes with two fans built in, and I was going to add two more on top. My question is do I need a dedicated CPU cooler or can I just run 4 of these? Might be a dumb question but I'm new at this haha

Then your choices for a case are only limited to itx, nearly every tower case you come across will support mATX and ATX, then you have Full Tower cases that would make that little motherboard seem out of place. Tons and tons of good options from $60 and up.

As others have touched on, a good modular power supply unit will not only be more efficient/reliable (especially if you want to OC anything!), it will help take care of cable management. I have always went for "full modular", semi modular will have a 'pony tail' with the motherboard, cpu, and gpu connectors rolled into one. It's nice to be able to route each PSU cable where you want imo.

So then there are your two main issues, cable management and airflow. You have a decision to make regarding the case, I understand liking how a prebuilt case looks because some do look nice. If you want to stick with that case you need to figure out how to mod it to increase airflow. Generally speaking, switching to a aftermarket case will be simple and increase your cooling performance twice over without having to mod a thing.

I use and always recommend EVGA PSU's because they generally perform great in benchmarks and come with a 10yr warranty: 550w Gold

If it were me I'd build in this case just for the hell of it for $40: CM Masterbox

Here's another case that would be good in your situation: Corsair Air 240

All depends on your budget.

Can you guys help me decide between these two cases for building my new Plex server? Which one would you go with and why? I wish I had a complete roadmap to share for my build at this point but I don’t.

To be clear I’m open to other suggestions. These two stood out due to ease of accessibility when upgrading components and cooling capacity. Thanks!
