Yeah, we have clients that have been buying these by the dozen for almost 10 years now and I do not believe a single part on one has failed... except for a few hard drives . Building a computer would be even better but the OP did not seem to want to go that route. If it were me, I would go buy the parts, stop by the store on the way home and grab a 6 pack, then watch youtube vids on how to build a computer, then build it. Once you do, you will never buy a pre-built again. Although, sometimes the Lenovos similar to that model (below) are on sale at BestBuy for $380.00 or so... but the OP would have to add an SSD.
Contact Microcenter and tell them what you are looking for. You can get one of their pre-build PowerSpec systems that will meet your needs. If you live in chase the rabbit land Florida, you might have to find a way to get there but otherwise, they will get you something very worthwile in the $500 to $700 range.
Micro Center is the place to find PowerSpec computers. With PowerSpec systems, you can be confident of a clean desktop with no bloatware or nagware pre-installed, U.S.-based Micro Center-owned tech support, name brand components, and great pricing and performance.
These systems are a real value. I have gone through multiple PowerSpec systems and they have always been good, reliable sytems.
Remember, these systems don't include monitors, keyboards or mice. So that $529 one with the i5 9500, 16 GB and 500 GB SSD might be just what you need. Or you could save up a hundred and fifty more dollars and get that i7 9700K system. It will future proof system performance for at least 5 years.
To be honest, with your computing habits even that AMD Ryzen 5 might fit the bill. You would end up a hundred or more under budget.
Since I only know the sales situation in Japan, I may not be able to refer to it very much, but some shops that sell pc parts sometimes provide an assembly service. @Vitali Ortzi
