[CentOS] Installing Centos 5 on one system and moving the HD to another....

I have a bug report in (0002288) on an install failure on my decTOPs 
(Centos 4.5 installed on them).

I have tried a lot of combinations and it is getting tiring.

What what happen, or rather how do I get the following to work:

Put my HD into a computer (Compaq SSF that I have installed Centos 5 on 
with no trouble), install Centos 5, move the HD to the decTOP.


Different Video card.
No PS/2 keyboard of mouse on the decTOP
INTEL vs AMD cpu

Could it work?
