What can I keep from this PC?

I got this old PC, it's got an Intel i5-6400 and 8 GB of ram. Pictures is the GeForce Gt-730, Gigabyte GA-H110M-A, and a 1TB SSD. What should I keep on this build or should I just buy a new PC all together? I'm looking to just be able to play games but I'm not very stressed about it being top of the line but I want it to be future proof for a bit.
