I'm fortunate enough to have a CyberStormPPC 366mhz/50mhz in my possession. I'm even more fortunate to have a Grex 4000D - and I would like to build a "modern"/classic high performance setup

I'm chasing recommendations for the Zorro/PCI slots. I'd like USB, Network, GFX and sound cards installed. There's lots of options and so on, and can sometimes make the head spin!
So, what are peoples opinions on the best overall options for the above cards?
