But that was before SWITCHED HUBS. When we had COAX (10B2) and 10BT on dumb hubs the quick upgrade was to split the LAN users over 2 hubs and use 2 NIOs.

Today, you run the server to your switched hub and let it aggragate the data for you.

I'll write "doubtful" on payback.

--> Next, it's rare to find NT 4 capable staff. I could take 10 IT staffers and give them 1 day to add the NIC on NT 4 and could safely bet that all 10 couldn't do it.

To me a sign this scenario is at work on that NT 4 box is that is not at the latest SP.
