Hey thanks for the help. I'll have to check the board specs later when I can, stuff is stashed away somewhere.
Sounds like I would be just fine using Leopard Server as a file server then, with a lot more pre existing support huh? Maybe I'll do that...
Yes I've tried running it as a NAS a couple different ways. With an old XP license, but while that works well when the server is up for some reason it always goes down or reboots for no reason... very odd. I used Ubuntu and that worked pretty well but for some reason also seemed to go down every 5-8 days or so, for no apparent reason. A reboot fixed it. Really annoying though. Using ubuntu I used a plug in, web-something, but I suck at networking and it was a PIA. I'm pretty familiar with get OS X to boot on different stuff and would rather get that up and running and have Apple's ease of use for the file sharing... and hopefully avoid all the obnoxious reboots and the NAS going down.
Does ATI vs Nvidia have any better compatibility with the newest cards, or does it not matter at this point? What about brand? I am wondering if I should go for a 4870/4890 or a GTX 285? And what brand (gigabyte, evga, etc.)? Which will be more compatible/overall easier? I will also need Dual Monitor support.
