Is this PC Any good?

[Archonaut]

A friend of mine is selling his pc, no special price for me or anything he sells it to everyone who is interested in it for 250,- euros.. It looked like there was something wrong with it because the price is incredibly low for this computer, 19 inch flatscreen and a really high tech keyboard + mouse. The only downside is that it's a selfbuild pc with no OS on it. Can anyone tellme if it;s any good?

So do you guys think I should buy it? Would I have some nice FPS numbers playing RO? Or is it just not worth it...
