I presume you don't need a display or keyboard ....

Well, prices depend on where you are and the quality of components, e.g. power supplies.

But as I am just buying a new system I have some idea. I would suggest an Athlon 64 X2 would be a good choice: that's a 64-bit system with de facto two processors which can be bought here with 2Gb RAM at well under your price.

They are all based on the same components: a distribution is just the packaging and installation tools. For performance it seems that systems based on gcc3 rather than gcc4 still have a small edge, but I would say local expertise is far more important. (At one point in the committee for a large procurement I pointed out that a 10% difference between two systems was 2.5 months' of Moore's Law, and that covered the spread of benchmark results for all the contenders. So if you want better performance, just wait a few months.)
