Will OSx86 Run on My Aged System and If So Which Distro

[transitionality]

Hi. I have an old AMD system running Windows XP and want to give it a new lease on life with OS X. I am wondering if it's possible and if so which distro I should use. I suspect my GPU may not be up to the task but if the rest will work I am open to uprading the GPU with something cheap off ebay.

Here are my specs:

- Epox 8K3A+ mobo
VIA Apollo KT333 chipset
4x AGP 2.0 slot, 6 * 32-bit PCI slots, 4 * USB 1.1 ports, 3 * DIMM slots (which support up to 1.5 GB of PC1600/2100/2700 DDR RAM), 4 * IDE-100 ports, 2 with RAID support

- AMD Athlon XP 1800+
Code Name: Palomino
Package: Socket A
Core Speed: 1536.8 Mhz
Multiplier: x11.5
FSB: 133.6 Mhz
Bus Speed: 267.3 Mhz
Supports: MMX (+), 3DNow! (+), SSE

- 512Mb DDR RAM

- ATI Radeon 7200 (R100) 64Mb AGP x2 GPU

- IDE HD

- Some other odds and ends - floppy drive, IDE DVD burner, PS/2 keyboard and mouse, etc.

Thanks in advance.
