I purchased this product to use as a Lightroom processing computer, in October 2021. It operated flawlessly,  until recently. It started BSOD, with a hardware error. After doing some troubleshooting, I determined that the 512GB Intel NVMe was defective. I contacted Kingdel, and after doing a little more troubleshooting, we determined that in fact the Intel branded NVMe was failing. Kingdel asked me to simply purchase a replacement on Amazon, and they would reimburse me. I purchased a 512GB Sumsung NVMe, loaded the OS back on, and everything runs perfect again! Thank you Kingdel support, and Brett Ming, for the excellent support and customer service.If you are looking for a small, quiet, yet powerful computer, I highly recommend this product. I also installed a 1TB SSD for storing photos locally. There is a mounting point, as well as cables to connect a 3.5" SSD.
