I sprung for a Raspberry pi 4 which is their newest board will more HP than the pi 3. They recommend Raspbian Buster (Linux 10) as the sanctioned O/S. It's a 6.8 Gb image file that you burn onto a MicroSD card. The dope on this board is HERE. Amazon has a selection of CanaKits for just under $100. You can pick what options you want.

I use this as a work station to run LibreCAD and the Libre Office Suite. The board supports 2 HDMI monitors, USB 3.0 (X2), USB 2.0 (X2) ethernet, wifi, bluetooth and upto 4 Gb of memory. So far the board runs well. Chrome is the default browser. You can load CUPS to get printers installed.

I use 32 Gb cards. There is an SD card copy utility which will duplicate a 32 Gb card in about 15 minutes. You'll need an SD card to USB adapter. Note that the HDMI ports are a micro style on the board side.
