Brands of product matter more than some off brand components. Id be sure of the manufacturer of the components. And often having these kinds of boxes come in my shop i find they have a 25.00 power supply components that are china made and cant even get on the shelves in north america. Be wary is all got to say.
these look like off the shelf components. nzxt case, small corsair fan, etc. You could build this cheaper, or have one of us build it cheaper. im def not a fan of the components they choose for such an expensive build.
