[CentOS] Hardware-independent server installation

I don't have a system similar to my active server, and I'd like to install CentOS to a new drive on a spare system and then load that disk in my server once it's configured with the services I need. How hardware-independent is a server installation? What should I look out for when doing this?

I've been using Linux on servers for several years and am a software/hardware integrator by day. It seems like this should be trivial but I'd like to know if I'm missing any obvious gotchas.

I'm guessing the biggest issue is associating eth names with actual devices (modules.conf?), since the systems are unlikely to use the same Ethernet hardware.
