I use this PC for basically everything, mainly gaming. Runs most games I play (Arma 3, Space Engineers, Rainbow Six Siege) at medium to high settings, 60fps without getting too hot. The only problem I have is that due to the small size of the case I have, it is pretty cramped inside. Oh, and the power supply is old.
Not including case, power supply and peripherals, PC cost $300 AUD when parts were on sale.
