Package came in well packed. Installed win10, stuck on MBR convertto GPT. Googled instructions to convert did not work for me. I installed the HD as storage on my other computer(Not through USB,but straight to sata connectors in the computer) and change mbr to gpt thru disk management. Win10 will ask to convert again but googled instruction worked this time. I am impressed with this computer.  It is working as well as my i7 with 24Gb of RAM. It is also very quiet, Overall this computer and the seller deserves 5 Stars.
