That really is one ugly case. I'm sure its good quality and does the job very well... still.
Decent times to be into PC gaming right now... a $2600 system is basically top of the line.
And yet for probably 1/3 the price you can get 95% of the performance for gaming. You could go with a 3700, the same MB, a good but less expensive PSU, perhaps a 5700 XT (I can't agree with their 2070 less expensive recommendation... where I am the 5700 xt is still a lot cheaper, $150-200 Canadian dollars min).... one of the many Samsung alternates like a Corsair that will perform as well or better for much less.
If I was building from scratch right now... I would go 3700 with a good 570 board, and as inexpensive as I can get away with GPU. It sounds like AMDs next gen chips will slot into the same 570 boards, and GPUs according to rumors at least are due for a long over due kick in the performance ass late this year (or early next now). Can build 90-95% of the performance of the best of the best right now... and in a year you grab a 4000 Zen, a Ampere or Big Navi... and sell the old ones or build a second machine around them with a 550 board or something.
If I were building right now I'm probably go for something similar (though I'd just get a 5700 XT instead of playing the waiting the game), but likely a B450 board over a X570. I just don't feel like X570 is worth it over B450 right now unless you really need PCI-E 4 and the other features exclusive to X570. Or I'd just wait for B550 to actually show up and build then.
