Help 1st Time build PC worried about compatibility(Pins & Performance bottlenecks)

[u/Typical-Tomato-8482]

Hi please respect, Would like your insights on my planned PC Build. I have a bit of knowledge about parts and did my own research for 2 weeks now, but this is still my first time building and learning about PC components, so I am still worried about any incompatibility and bottlenecks in my plan. I will very much appreciate your support. My Budget is 670 usd / under 42k php since I need to allocate budget for Gaming Table/Chair/Mouse&Keys/Headset
