The first PC I built ended up breaking after 2 weeks. So with it being within the return policy I sent back the CPU and mobo at the time being a pentium g4600. After waiting for a week and receiving the parts the PC would not work. After 2 months of trouble shooting and RMAing parts it turned out for the ram I had G.skill aegis ddr4 2133 mhz was "Intel ram" and was not compatible with my computer. The computer works now and I absolutely love it gets great performance on games. 10 out of 10 would recommend the parts.
