I have an HP Probook 450 G3 that would fit your needs that can obviously be mobile when needed. Some specs are: a bright 1080p screen, Windows 7 Pro(Windows 10 Pro can be installed if you want), i5-6200U, 16GB DDR3 Crucial, 1TB Crucial MX500 SSD, DVDRW Drive, wireless and wired internet capable. Great condition for its age and definitely a capable office PC. It was used for launching VMs throughout its life. $200 shipped sounds fair. I can throw in a BNIB wireless logitech mouse and BNIB Samsonite laptop backpack to complete the deal. Let me know what you think.
