Incomplete used build advice

I was looking to get mid rangeish build complete before prices get too bad. a friend of mine has offered to sell an machine of his that he took the gpu and drives out of.specsamd ryzen 5 5600g2 x 8GB 3200 ddr4 memory550w gold superflower psuasus prime b550m-k motherboardatx case with fansno gpuno storagecan i work with this build or would it just be better to start from scratch. willing to go for a more expensive build if it would save from upgrading during the worst of the memory shortage. most demanding games i'd play are from-software and kojima-studio releases. have a 1080p monitor so i won't be playing at any resolution higher than that
