The desktop sounded good on paper for lightly used home PC. When it arrived in May, it said no system drive detected. I contacted the seller StallionTek and got a replacement. But the replacement had the same issue. StallionTek instructed me to reinstall Windows 10. That got me going for a while, even though the PC still crashed once in a while. By early September, the PC hit the same 'no system drive detected' problem. After a few reboot, it lost video signal as well with loud fan noise inside. I suspect Motherboard is dead.This time, StallionTek would not help unless paid extra for labor and parts. After all these troubles, I really don't feel it is worth it anymore. Only if I knew, I would have returned the item in May.
