Not a bad system. The Cryorig is actually better than the Coolermaster. The stock heatsink is fine, but under load like gaming and if ambiant gets high in the summer, it can have a hard time keeping up.
The only thing I can see is the PSU. I'd recommend a jump to the B2 series over the B1. There is a big difference in quality between the 2. Even a 650W if that's available other than a 600W. Maybe B2 isn't available in a 600W. Your system will take around 450w, so a 550-650w minimum is recommended. I even like to jump it a bit higher since a PSU can last 10 years, I like having it large enough to handle anything I throw at it in the future like a second video card. I prefer to go 750W. I've often seen the G2 selling for the same price as the B2 so even that is recommended.
Another thing is the 120GB SSD. With you installing games that 120GB will fill up fast. A 256GB is more recommended although a 120GB will work fine, but with limitations.
