Id say thats the average price your looking at for that type of computer from a shop but i got a 16GB RAM 500GB HDD no GPU and a worse case for £350, all i need really is a better GPU and im set for my gaming rig, i wont be adding anymore RAM im good with my HDD atm as well, i will probably end up just building maxed out computer 32GB RAM 4TB HDD best GPU and case and PSU and shizz when i want an upgrade which i imagine from building it myself would cost as much as that rig your buying there but because you dont want to build it, that an average price be hard to find a better price in my opinion
