badbyte wroteOk, I see that you never set up a firewall, webproxy or some sort of server. If I'm wrong thenI wouldn't be surprised that it would be a MS Windows Server 2012 or something like that, which requires hardware.
I apparently expressed myself in a wrong way. The reason why I pointed out to a Core2-XXX was to save some money under the assumption of different aspects of the user. Aspects like private or professional use which is the main criteria in this case.
The discussion went off topic and now we are here.
I think it's a great idea to use such computers as firewalls, because you can whatever junk you can find and it will still run. But, when it comes to someone who wants to buy a computer. I'm completely against the idea of buying or using used hardware when there's new hardware for the same price. If I buy used hardware, there's a chance of something going wrong and at the end of the day, it's your reputation on the line, because it was your recommendation. I'd rather put a few dollars more and get new hardware and have nothing to think about something going wrong. Even something goes wrong, I'll always have warranty to cover my back. So, I have nothing to loose at the end and my customer/client will be more satisfied.
Again, when it comes to stuff such as firewalls, file servers, proxies, I don't see any reason to buy new hardware that will be far more expansive and do the same job. CPU's can last forever, and there are certain motherboards (Like my Maximus V Formula) can last up to 15+years due to high quality components, even though the manufacture's warranty is only 3 years, the product is made to last far longer.
