Free Ryzen 5 5500 and Motherboard

My friend recently upgraded his pc so he offered to give me his old ryzen 5 5500 along with the mobo which supports ddr4. I have found a RX 6750 XT open box for £310 so would only need the remaining parts. I would like to keep the budget low without cheaping out on any parts. This will be played on 1080p for now until I upgrade my monitor to 1440P. UK based. Thanks in advance
