I have 2 Dell OptiPlex 9020 computers available

Intel i5 CPU 16gb memory Windows 10 Pro 500gb ssd / 250gb ssd

One of the computers has the WiFi module the other does not but if you plan to use the built in WiFi you’ll need to order an antenna or alternatively just buy the latest and greatest WiFi 6/7 USB adapter which would probably better anyway.

I only have one power adapter but a second one can be purchased on Amazon for less than $30
