Very neat! Do you mind describing what settings you used and a bit about the environment where you shot it?

Take a look at levels.fyi. You can sort by position, company, and location.

If you have reservations about building a PC yourself due to lack of experience, there is nothing to be worried about. It is honestly a lot like building a Lego set. Most components are difficult to attach improperly. There are decent pre-built PCs out there but you will be paying a premium. You might even be able to save money in the long run by hiring a local shop or a friend with some experience to put a PC together for you.
