Here ya go a little help:

iPC (10.5.6) is probably the most supported osx86 distro (yes that is right) out there. It's got the most up to date and comprehensive list of drivers ever put together. Another good distro is Jas 10.5.4.

So stick the torrent on and while your waiting for it to download you need to research about your computer.

The specs your posted were a lot of mumbo jumbo copy and pasted from the manufacturers website no? There are hard facts you need to find out about your pc before you can even try installing iPC, I've listed what I can below to try and help you.

They are:
1. What Processor: You have a AMD Sempron 3400
2. What motherboard make and model: You have ECS 761GX-M754 (not sure though?)
3. What onboard ethernet your motherboard has: You have SiS900 PCI Fast Ethernet
4. What onboard sound your motherboard has: You have AC'97 Sound Controller
5. What sata/pata controllers your board has: Hmm not sure here - you will need to find out as it's darned important.
6. What Graphics: You have GeForce 7300 SE

Now you will need to track down the drivers for the sound, ethernet, sata, pata, and graphics. I'm not sure if they all have drivers. You'll have to find that out. Look on pcwiz's blog to see the list of drives iPC has, and try to track down drivers via insanelymac.com.

If you think you have them all try and install ipc, follow one of the many guides that are around. It's tough and you'll probably end up wiping your hard drive. Back everything up and just go for it.

The alternative is of course to build a box yourself with parts you know will work like the asus p5k series or the gigabyte p35-ds3 series. Intel processors are always less hassle with osx86 and so is sata. You may have to upgrade.
