I'm no expert on PC recording but its a fairly open question. The immediate answer would be, it depends what type of music you're recording.
For example, to record live drums you'd need at least four mics (two of which need to be overhead condensers) and a mixer. To record guitar/keys etc you can use the same mixer.
But however you do it, you're not going to be able to do it that well unless your PC is up to the job, and that means a proper soundcard for multi channel recording.
If its a one-off it'd probably be cheaper to hire a pro studio. I was in a studio recently and it cost £120 for 5 hours, and we managed to get four songs recorded and onto CD.
