Has anyone here every though of building their own Mac(Hackintosh?)

I was just looking around InsanelyMac and found a guide on building your own Hackintosh.. just for kicks I researched how much it would cost to build your own Xmac.(The computer everybody wishes Apple would offer) Using Newegg this is what I came up with:

Newegg
Antec Sonata III case with a 500W PSU - 114.95
Open Box: Intel Bad Axe 2 - 119.99
EVGA-Geoforce 7600GT - 89.99
Intel Core 2 Duo E6550 2.33GHz 'Conroe' - 169.99
A-Data 2GB(2 x 1.0GB)240-pin DDR2 800(PC2 6400)Dual Channel Kit - 42.99
Seagate Barracuda 7200.10 250GB OEM - 65.99
Lite-On 20xDVD Burner IDE DH-20A4P-04-OEM - 24.99
Total=$628.89

This is just building one on the cheap side.. for a $110 more I could get a 'Kentsfield' processor. The only limitation I have heard of on this is that they haven't yet figured out how to get the microphone port working, but for most people thats no big deal.
