Is this computer any good?

Yeah, though that's quite a lot to pay for it. Could build a computer equaling that for about �700-800... but if you don't want to build, go for it. The only thing which seems a bit lame is the hard drive, since it's only a 5400RPM and not a 7200RPM. The PSU as well seems a bit low wattage for those components, but if that's what they believe it needs, then I wouldn't contest it.
