Oh damn, I was about to reply with a part list that I would recommend. A B660 is under kill for a K sku CPU, you lose features. An air tower cooler for the CPU will do, but for the cost of the one you picked you can get a cheap water cpu cooler. Don’t get me wrong, the RTX 3080 is a great GPU, but with next Gen GPUs right around the corner and with that price the value just isn’t there. I would recommend an RX 6700 XT instead. I also picked a cheaper kit of memory with the same speed, latency, and capacity. A 1000W power supply is overkill, a good 850W will do the trick. With your savings I would buy a faster and bigger NVMe SSD, as well two SATA III HDDs to run in raid 0. they aren’t anywhere near as fast as an SSD, but they are cheap, high capacity, reliable storage for games, large applications, and any data that you don’t use often that doesn’t need to be on your high speed SSD.
