My first pc was from a local shop as well and i had a really good experience. I wouldnt do it now that I can and have built my own but id recommend it over a prebuilt.
Personally I just don’t have the patience to build my own computer. A big part of that is I was really particular about the case, I wanted the meshlicious small form factor case and small form factor cases are pain to set up efficiently. They did a great job putting it together cleanly and since they did such a good job it’s a lot easier for me to upgrade if I did it myself and did a less professional job.
