ahh 1200 Towers are a love & hate thing for me

...I went through all kinds of stuff to get mine up and running stable with all the pci cards and I remember following this post/thread over at amibay

...oh and do yourself a favour and buy the P96 from Individual Computers website as it fixed up some artifacts/ little bugs on my system anyhow
