As a previous reviewer stated, I was also wary of spyware and boot sector viruses so before I booted to the installed Windows 10 Pro, I booted with a USB drive that had several virus scanning programs installed - none of the scanners reported any viruses on the SATA hard drive. After that, I booted with the installed drive into Windows 10 Pro and I was very surprised how fast everything was.After setting up Windows 10, I replaced the Windows 10 SSD and installed a different SSD and loaded Red Hat Enterprise Linux (RHEL) 7.6. Once again I was pleasantly surprised by the speed of the install and all of the components of the computer seem to be recognized and have good drivers. Since I currently program using RHEL 7 and use 5 RS-232 serial ports in my system, this is a great substitute for having to use an old laptop with a USB to 8-port serial adapter that I was using.If I notice anything out of the ordinary, I'll update this review but so far I am very pleased with this purchase.
