I bought this HP 8300 Elite Small Form Factor Desktop Computer intending to use it for a clean install of Linux Mint. The computer was refurbished by and shipped from My Technology Geeks in Kent, Washington. It arrived within a week of ordering it. I was very pleased with the external and internal condition of this refurbished machine. Outside showed very slight sliding wear on the top and sides but the plastic front was in perfect brand new condition. One rubber foot pad was missing. Inside there was not a speck of dust and it looked brand new.I booted up the Windows 10 Pro it came with, plugged in a wired internet connection and was online. I also used a Panda Wireless PAU05 dongle and Win10 recognized and installed it too, no driver problems. I can go online either wired or wireless no problem.  I went to YouTube and found a video by Poolarity -- Life Hacks, How Many Usage Hours on Your Hard Drive, with a link to a free diagnostic tool by hwinfo.com. Great! I ran the diagnostic and found my hard drive had 31,669 hours or about 3.62 years on time. Not brand new but what do you expect for a refurbished machine? It will probably outlive me considering how much/little I actually use it.Finally, I have been a dedicated Mac user for about 15 years and looked down my nose at Windows. After using Windows 10 Pro to check out this machine  I completely changed my mind. I now love Win 10 Pro and will keep it. My original intention to do a clean install of Linus Mint will have to go on an external SSD and dual boot this thing. Five stars.
