[ale] What are the minimum requirements for a CentOS server to learn on?

[Robert Owen]

Hi, All, I haven't posted to the list in several years, so please
forgive my "lurking" most of the time. My son-in-law is studying at
home for the RHCT exam and wants to know what motherboard and
processor, and minimum amount of memory he needs to set up a server to
learn with. Initially, it will be for a home network, but later, maybe
on . . . ? It must be able to set up virtual servers, too.

Thanks for any help given.

Bob
