I'm looking at building a PC for under $650 and these are the parts that I looked at, I'm genuinely not looking to play the next gen

the most intensive games i think i'm going to ever be playing are borderlands 4, cyberpunk 2077, that new lego batman video game, and some sim racing. honestly i'm okay with 30 fps, 720p. i know that's not what a lot of people understand when they hear games but i don't know. my current gaming pc is an hp elite desk 705 g4 which is not a gaming pc in the slightest and i still make it work. i'm looking at this and i'm thinking "this is an upgrade."

Basically I play a lot of old school titles and first person games I could care less about the multiplayer landscape to be honest with you. If I even touch a call of duty game it's purely for the story and to mess around with bots or play zombies

The only thing I can think of salvaging from my current PC is the nvme and I have some USB 3.0 drives I have almost a terabyte of storage and total that I can put into the new pc the thing is though is I've never built a PC. I could probably do it with some tutorials I'm pretty technical I've built other things.

Just really want to know is this reasonable for what I'm looking for?
