I purchased this machine for audio production. When it arrived my audio interface had a crackling noise. I was told it was because it was old and unsupported so I bought a new one. The new one wouldn't work at all. I spent a long time with tech support trying to get it to work. It would not. I bought another interface. it had crackling noise too. Again, hours and hours with tech support trying to get it to work. It would not. When we tried to tune the machine to increase spread it would not restart. The technician said that the processor was only working at a fraction of the speed that it should.CyberpowerPC said it was defective and needed to be shipped back for repair at a $90 shipping cost to me. I paid the money and sent it back. Weeks later the machine came back to me in exactly the same conditioned.I asked CyberPower PC for a refund of the $90 and to return the machine. They basically said no. Seems to me that if the machine is malfunctioning out of the box, they should be responsible for paying shipping costs. Yes it was outside the 30 day shipping window but I had been with tech support the whole time trying to get it to work. I haven't used it outside of troubleshooting one time.
