This is my second purchase from Skytech USA.  This time a home computer.  My experience with renewed computers started when my office at work suffered a direct lightning strike, ripping through all surge protectors.  I ordered 5 refurbs from a couple of sellers.  Every one is working better than the one it replaced.  Only one stopped booting and had to be returned, which was easy.  I purchased a new one from Skytech and it came in perfect.After that I decided to replace my 11 year old home computer with this HP from Skytech.  Incredible price.  I couldn't even buy a license for Windows 10 at that price and it came in perfectly with Windows 10 Pro, which I need for remote working from home.  I'm not used to working in SFF, but I downloaded the manual for the HP Elite 8300 and the photos made it easy to pop off the DVD and fold back the power supply to get at the primary HD and a spot for a second one.  Prior to that I installed Macrium Reflect free version, plugged a 240G SSD drive into one of the USB 3 ports and cloned the drive that came with the HP.Then I simply popped open the case, put the SSD drive into the primary spot and moved the 500 G hard drive to the secondary spot under the DVD.  Everything went smoothly, I rebooted and instantly had Windows 10 Pro licensed copy on my SSD drive.  Extremely fast.  I ordered another 16 GB of RAM because I'm not used to working with the 8G that came with the computer.So I'm only on Day 2, but I'm extremely happy with this purchase.
