Thoughts on this CH160 Pc build?

Upgrading my GPU, on top of buying a PSU and new CPU cooler.

My 3070 has become defected, It was a good 5 year run out of it. Hence the upgrade and why you are seeing an older Mobo paired with a 5800x. Also had the NZXT H1 Mini which kinda showed it's age, a AIO that broke down and almost melted my CPU back then. (Heard a lot of issues with their built in AIO), It's fucking junk, so can't recommend the case. AS well as the tampered glass that broke when I transported it over seas back home :p. I jut think my small factor PC build needs a quick overhaul whilst keeping the core Mobo,CPU,and RAM in.

Wonder if this PC will hold up for 1440p gaming etc.
