This unit arrived ahead if schedule. I opened it up as soon as unpacked to see how it looked inside. Nothing loose, everything pristine, no dust, dirt etc. This looked like it just came from the factory new. Booted up perfectly and only had to register win 10. I needed to transfer 2 other hard drives from the failed PC this one was replacing, which went smoothly. Also had to install a fax modem card which was plug and play. The unit has been on continuously for the past 3 weeks or so with no problems. Would definitely recommend to anyone.
