I'd buy a Mac Pro cheese grater case, and stuff it with faster non-apple used parts, as in, YES, I'D GO HACKINTOSH. Throw in some ridiculously fast RAM, the fastest i7 processor there is, liquid cooling, overclock the sucker, Dual 5870s, a plethora of SSD drives in RAID0 using a proper non-apple branded POS raid card, and a 2tb drive for storage in the secondary bay.
I'd pay top dollar to have the inside of a mac pro case get refitted for a better PC branded motherboard and better ram.
I'd pay someone to do this for me, money buys everything, right?
If I had the mac pro standard comp, i'd just load it with the fastest intel SSD's in RAID0, get some flashes 4890s in crossfire and accelero s1 cooling (silence!) and again a 2tb drive in the optical drive bay.
As for LCD, i wouldnt even bother with any of the lame apple 'cinema' displays. I'd get a proper Eizo S-IPS matte finish LCD monitor;

As you guys can see, the only thing worthwhile having in a mac, is the operating system itself, nothing else is made by apple.
