The 9100f is a pretty good budget CPU. It has very good single-core performance (for the price) though it may not play nicely if you throw the latest greatest games at it due to it just being a 4c/4t CPU. For the money, I don't know of any better choice.
The motherboard is quite literally the cheapest you can buy, but it doesn't need to be anything fancy for a locked i3 and some basic ram. I don't see why it would be unreliable. At least it's not some Chinese unbranded board, though AsRock isn't amazing.
The ram is nothing fancy, but it's fine for the build and should give proper dual-channel support. I would assume it has a lifetime warranty given the brand too.
The CS900 isn't the worst you can get. For the price, it's pretty good. It is dramless, but the controller itself has double the cache of most controllers which helps to mediate some of the issues with dramless drives. Its TLC, and not QLC, which is a point in its favor. Honestly, I have used several cheap dramless drives and I am unable to notice the difference between them and my $120 NVME for basic usage. Reliability on a dramless drive is a point of concern, though my brother has used a BX200 for like 5 years with no complaints, though it is now a secondary drive.
I have yet to have a single bad experience with PNY. I had a PNY GTX1050 and never had an issue with it. I also had a PNY GTX770 recently and it was pretty quiet and was still working well all these years later. I have used a few PNY flash drives and only had one PNY USB drive fail and Customer service was easy to deal with and prompt which is far better than the service I received from Kingston when my A400 died. I actually have a 500gb CS900 coming in the mail today for a HDD replacement in an older laptop.
The RX570 is average. A solid performer in general.
The SeaSonic S12iii isn't amazing, but I would expect it to reliably power the system. Its a budget system and a budget PSU to match. Should anything go wrong you would have great customer service. Alternatively, you can get a CX450 for $10 more, which would be a good idea.
While I haven't used the case personally I have a friend that uses that case. It's not very good, but you would expect that for the price. It gets the job done and there really isn't anything to fail in a case, other than a fan.
All in all, it would be a pretty decent gaming PC for the price. Should run any game you need, though you will have to keep your expectations in check if you want to play very demanding modern titles. You get what you pay for.
For $15 more, you could get this which would be my pick, though the last build is the best you can do with the price, in my opinion.

Better PSU and a nicer motherboard with an m.2 slot. The SSD isn't an issue in my opinion and cheap cases are fine.
