Assuming nothing has changed, it's running on a "3.0 GHz Core whatever, 12 GB RAM, 64-bit FreeBSD 7.1."

Upgraded on 4/19/09 from a 2.4 GHz Pentium 4, 4 GB RAM, 32-bit FreeBSD 5.3.

Yeah, well, this is a middle of the road server these days. I have a 16-core server with 64G of RAM as a dev server at work. They get even more powerful than this, too.

Not saying pg should spend any money on this, though. A redesign of news.arc will stretch the hardware a lot further.
