get fastram, kick 3.1 and buy a network and a Indovosion/GFX Card.
If you have a Network Card you dont need a Modem or USB.
For best Compatibility get a HcX Floppyemulator and your Floppydisks are not longer needet.
For a PCI Bus System you need a 060CPu.
With standart 030 you have no fun with this !
