The HP z240 pc works great. I bought two. One at 17.24 after a credit and sent to a relative  : )The other was a total of $135.77 which I have.You turn on the pc and it starts the install of Windows 10. The SSD was 1TB and not the 500Gb one as in the ad  : )The SSD has 4 partitions. You can download the free EaseUS Partition Master to view more details then Manage from This PC.System 100MB Bootmgr, Windows Recovery 750MB, OS (C) and HP_Tools 5GB <- holds biosThe one I bought for myself was from Sept 2018.A review from 2016 said suggested price of $3,200!!I bought a pair of SATA cables for $5.46 and plugged in a 2nd 3.5" 7,200 rpm hard drive. The pc has room for 3 hard drives. You can buy the LeFix 5 Pack Screws Isolation Grommet Mute Mounting bolts for HP 3.5" needed to secure the drive for $6.99 at Amazon.Use Winkey1.4 to view your serial number/product key and copy it for later installs if needed.Backup the hard drive image with Macrium Reflect and also buy at Ebay a copy of Windows 10 (less then $50)
