Need recommendations for a PC/Windows set-up to mine with GUI minner

[Bitcoined-Me]

I have a PC with windows running GUI miner. My speed is usually around 450 khash/s. I've been running this for a week but haven't had any Accepted or Stale increase from 0. Should I have by now with this speed?

I connect to Slush's pool and my account set-up looks correct.

I'm now thinking of buying a PC specifically to mine Bitcoin from home but need some recommendations on the spec. My Internet connection is fast and stable.

I'm mining for fun/hobbyist as I know it's hard to mine for net profit with today's electric costs. I still want to mine Bitcoin regardless.

While it most certainly can be a a learning experience, mining Bitcoins using your CPU is terribly inefficient these days. Even the older generation of Block Erupter ASIC miner (USB stick) will produce in excess of 300 Mhash (not quite 1000x of what you can do with your CPU).

You can have some equally interesting learning experience using a whole lot electricity in the process.

Mine a X11/Other alt coin and sell them for BTC you will make more BTC that way.
