How is this pc build?

I'd put in a larger SSD, 120 is OK for the OS and a few games, but anything over a few new games and you'd be wanting more room. You can install the games on the regular drive, but not getting at least a 256 gig SSD in a build like yours is compromising a bit too much to save very little compared to the overall cost. It's like spending $1,000 on a computer then buying a $5 keyboard and a $5 mouse to use with it.
