By all accounts, this is a ossc... All the ports, same visual build and even comes with a printed booklet ripped straight off the internet. But it's not an official OSSC. Some of the components aren't of the exact specifications of an official OSSC and parts of the construction aren't of the sane quality. Plus it took a whole month to arrive. Would I recommend it? No. You can get a better build from official suppliers for less.
