Here are a
couple I've found. Again, the concern is them inevitably dying.
And they
will die. Usually it is a drive failure which isn't super difficult to repair, but there is some technical know how required. I've known one guy that runs one of the early PS3 systems and he is an electrical engineer (not that you need to be THAT skilled) and he has done multiple repairs but his system still works.
That first one with the noisy fan is probably going to throw a bearing sooner rather than later. So you'd be on the hook for a fan repair which is not too hard, but consoles are not exactly designed to be cracked open once you buy them. As for that second one:
PLEASE PAY AS SOON AS AUCTION ENDS SO WE CAN PROCESS YOUR SHIPPING AS SOON AS POSSIBLE! ALSO, PLEASE DO NOT BID IF YOU CAN NOT PAY! THANKS!
That makes me run away from a seller pretty quick. No shit you pay when you buy. Someone really wants that money now and they had to put a redundant message in giant red letters to let us know.
That first one probably isn't a terrible deal if you've got 200 bucks to spare. As long as you aren't pushing off rent or cutting into your groceries, go for it.
But you're still here for the PC, too. I think you should absolutely get the new PC if you can. If you can compartmentalize the PS3 emulation issue, I think you're in a good position to get a new system that will see you through the next couple years. Our technology nowadays is
so good that you can buy two generations old and still run everything. I like your budget and I agree with other users that you should look into prebuilt mid-range systems. The custom built PC market had its moments where you could get a real deal, but at least for the last several years I would struggle to build you a system and come up with a price tag that would be competitive with a pre-built. Anymore building a custom PC yourself is strictly for enthusiasts or very specific use cases and the math doesn't work out like it did 10 or 15 years ago.
Feel free to ask any questions if you still have them. I have all weekend.
