Among brands that aren't overly expensive, Skytech and CyberpowerPC have good reputations. (Skytech is a bit cheaper.) But most hardware problems happen either right away, when the computer is still under warranty; or a number of years in, as one component or another wears down. So as long as you take care of your system, you should be fine.
It's understandable why you'd be indecisive—after all, this is a significant purchase, and it's not like you can test-drive the computers before buying them. Maybe it will help to see a progression of increasingly more powerful, and more expensive, systems from one company. The processors and graphics cards get better, but the memory and hard drives are the same. (The last one has a better motherboard too.)

I found the
first and
second ones on Amazon too, although the first is much cheaper on Skytech's site.
As for Cyberpower, this one has the same processor as the first Skytech and the same graphics card as the second:

This Cyberpower has a processor that's equivalent to the first Skytech and the same graphics card as the third one; it also has more storage, if you think you'll want it and would prefer not to install a second drive yourself:

The other brands I saw on the various sites I checked all offer variations on the same configurations, some systems with larger HDDs, a couple with 16 GB RAM. But of all the factors to take into account, memory is probably the least important, since it's the easiest and cheapest component to add later. Processors can be replaced but only with difficulty, and you can't switch between Intel and AMD without getting a new motherboard and basically rebuilding your computer. Graphics cards can be swapped easily enough, but the GPU is usually the single most expensive component. As mentioned earlier, hard drives are easy to add after the fact. So in your position, I'd get the best CPU and GPU I could reasonably afford and count on being able to upgrade the other components later if necessary. But this is about what you want, and what's worth the money to you.
