Hi.

Could you please give me advice about issue described below.

My friends have to use a PC with old hardware for a few months. They've 
got 128MB of RAM, 20 GB hard drive; Pentium 3 processor.

At the moment they have windows xp running on it, but it's very slow.

What are the system requirements for CentOS 2 or any other version of 
this OS that may be suitable?

Can you recommend any other Linux distro that would be easy to install 
and to use?

Thanks in advance for any input.
