Arrived within a couple of days using cheapest rate (£2.99). I have bought the pi4 2gb and 8Gb. (2GB for openmediavault and the 8gb to experiment with Operating systems.).Guess if you're buying Pi you have some idea how to setup. But if not there are plenty of tutorials on youtube. A basic purchase would be a mini hdmi cable, and power supply. Possibly sdcard as you'll need to update eeprom (easy to do) so it can boot from usb. Not sure if there is a basic tutorial on their website for setup especially for the pi4 but nevertheless I highly recommend PiHut as a reliable source for anything Pi related
