Help me lazyweb; you're my only hope

Is there any way of getting bluetooth on a PC withouth using a USB dongle?

Frankly if it needs a dongle, we may as well get some other wireless connection (or even a cable) as the whole point is to reduce cables. Can we get a card that fits into the innards of the PC like there is on a Mac? (And no, we can't afford a Mac).

Any views?

Edited to add: It's not for networking, it's for a keyboard and mouse, telephone (and maybe the Mac laptop, so a small element of networking), I suppose.
