Looks like your mobo only supports AMD Crossfire.

looks pretty solid but you probably don't need the x570 board. Go for a nice b450 or x470 board instead

You should be fine to slot it in but be warned that your windows may be deactivated because of new hardware

wouldn't that be a downgrade? or maybe a sidegrade?

maybe you're drawing too much power from your PSU? What's it's wattage and what other stuff is in your system?

A card that's used to interpret wifi signals for your computer I think you can change them out for upgrades n stuff not really PCIe

Nice Choice! Edit: Lian-Li is making a O11 Dynamic XL which should be coming out soon

They have more features that people might need. For instance x570 has PCIe 4.0 which people use for storage Edit: x470 and x570 mobos might also have better VRMs. idk much about them though. Refer to the Motherboard tier list for that

The coolant should be fine, it's just used to transfer heat to the radiator where it's released into the air

3600 is the best bang for the buck rn.

look for a plan from your ISP

A modem is just kinda like an interpreter for the cable signal from your ISP

but this is desktop cpus instead of mobile cpus... there's gonna be more performance
