It's got some nice components in there for sure. But I think 250gb ssd is a bit on the small side (I know it has a 3gb normal drive, but you want games on the SSD and they can take up some space).
I also don't like it only having 16gb of RAM. With a build that high end, it really should have 32gb.
Also, that case is hideous...
Now that being said, they're not overcharging for the parts by a lot, so it's not a terrible buy from that perspective. They do include some parts that I would leave out (Windows license, optical drive, 3gb normal drive), so it's possible to get the same performance for less.
So is it worth it? The components are good and mirror fairly well what I'd get myself if I were to build a new system. But the 1070 is a more price efficient buy than the 1080, so if budget is a concern I'd look for something including that.
Also note, Inet has the option to build a computer from custom chosen parts (for 800sek I believe), giving you the option to customize a bit more if you don't want to put it together yourself. If you don't mind assembling yourself, there are cheaper versions of the 1080 out there (by almost 1000 SEK) compared to what Inet sells, so there is money to be saved there as well.
