Forget warranty etc codes work sometimes
More ram needed,Quite expensive.
Do they come with 12 months warranty included? I am sure better deals can be had with patience and a bit of luck. Just like with purchasing most things. Perhaps not as good a deal as the 9020 systems from ITZOO. The code, if it works, will take £17 off. £153 for a system which is ready to go, seems good with a legit Windows 10 Home Premium 64bit license.
The processor goes for about 70 quid on ebay, so the £100 left over would be more than enough to cover the rest of the parts in this system. Sorry but it's cold from me. You can get exact same setup but with 4gb more ram for cheaper returbs on ebay.
