I was part of the hardcore build it yourself crew for years and years, but I find now that for the last 10 years or so now, and especially with the death of places like Fry’s and all the bullshit Newegg pulled, it’s way easier and cheaper to buy a pre-built box that’s maybe 90-95% there, then tweak what you need to tweak.
Get that manufacturers warranty and forget trying to part it out yourself.
$3,500 here.
