It will do fine, though you will run short on GPU memory from time to time - just spin up a cloud instance when needed. Price seems high - I could duplicate the parts for $1200. It’s not too hard to build a system, and you get to make sure all the parts are good quality. Prebuilt system power supplies may not be as stable as you would like for intense workloads.
I don’t think building a system is hard, however I thought there was a risk of screwing some pieces is nof done properly ? I’m not sure I want to take the risk…
Also, perhaps you can get the parts for that price because this is America, and I live in France (20% value added tax ^^)
The keys to a successful system build are making sure all the parts are compatible (which partpicker addresses), not forcing anything into place, and making sure the CPU heat sink is properly seated. You could also see if there is a local computer shop that would assemble parts for a reasonable fee.
