This is a bundle deal that comes with an Asrock b450m ac/r2.0 and 16gb ddr4-3200 cl16.Note this bundle doesn't come with a cpu. It's in great condition and makes for a great budget pc. It was kept in smoke free home and was well taken care of. I'm selling because I have too many computers that I've built over the past year and need to down size my inventory and will be starting with my lower end budget pc's first.
