The ISA NIC's would made me worry.
An ISA Ethernet NIC with a rate of ~ 1 MB/s utilizes the CPU up to
50-70%
(regardless of the CPU speed). On practictal tests the ISA bus maxes out
at around 3MB/s at 100 % CPU load (unless the ISA device does DMA)
For more than average network traffic, I'd put some cheap PCI NICs in.
You
should have at least 2 PCI slots free. Unless you are using this machine
also as a workstation, you could throw out the PCI VGA adapter and just
use a plain old ISA one, so you will gain another PCI slot.
