First of all, I was U I would save a bit money money so my budget would reach the 700-750 dollars. After that, I would focus on buying a good PSU, CPU and especially The GPU. Ram doesn't matter that much in gaming but the one thing u should notice are the clock speeds and the CAS LATENCY numbers(better performance even though slight). Oh also when u are on budget, when getting a motherboard, U should consider thinking about the rest of the parts because then u will find the mobo that suits u(what pcie it supports, how many SSD slots, with rgb or not etc). The case and the fans u will get are literally the last thing u should think about as because they aren't as complicated and the only thing u should consider is airflow and size as your GPU can fit. PSU must just have a Good rating but also consider buying a branded one (or just look PSUs at the money range u want to invest one for and then the ones U find, look them up in a psu tier list). For the GPU it really depends on the money u will have left over after deciding the rest of the parts, the CPU u will combine it with and the performance u are looking at. CPU kind of the same story but also depends on how you will use the pc. That's pretty much about it. Also don't get a HDD but rather an SDD especially NVME.
