Okay, so new server is up but we ran into some weird trouble last night...
The bad news is that I am still not entirely sure what the flock is up with it.
The good news is that it's not MC crashing, or disk related, so the server is all good to go.
I just replaced the domain controller/DNS/DHCP, as well as put in a new firewall, so I am trying to figure out what the hell happened.
Hope to have it resolved today.
