The system only has a 32GB drive, you will be installing some very small games on that. For performance there is no single answer since there are many games out there. The 3Dmark 06 benchmark put it in the bottom 5%, so even games from 2006 are not going to run well. Just expect it to be very slow or not playable in general terms.
From what I see on that system it's also passively cooled so no fans. Trying to stress the system with running games on it could cause issues with overheating, performance throttling, shortening lifespan of components.
