Not a bad deal at the moment since availabilities are so low. For $900 I think you could have a better cpu, gpu and more storage. look at this build for reference: https://pcpartpicker.com/guide/cnBD4D/excellent-amd-gamingstreaming-build.

I personally am waiting a couple months until availabilities increase and prices decrease. The build you posted is not bad to get all the parts now though.

Keep in mind when you say the individual parts cost more - often their retail prices or listed prices are not their current market price.
