mrtricks: Why don't you do a self-build? It's ridiculously easy, if a little tedious.
Having said that, I guess it depends on what you're going to use it for. Personally, I get anxious if I know my PC isn't configured optimally. If I bought a pre-built system I'd have to take the thing to pieces just to see if it was put together properly (and using quality components) :)
One barrier to me upgrading is that I'd have to buy DDR2 memory. Now that Corsair have some low-latency RAM available (albeit, running at 2.4v!) I would get annoyed with my PC if it was crippled by slower RAM. Problem is, 2GB of low-latency costs about £340. ouch.
