Hello all:

Am following Roberts advice and to make a long road shorter before jumping
on the learning curve of the spilling out of the computers from their cases,
which i will now do in a second go around, I am getting ready to install the
operating systems on each of the 3 computers and 1 laptop(should i even
include the laptop?)

Currently I am using the latest version of Mandriva linux. However this is a
full end user install and comes with a lot of stuff.  I assume I need a
simpler install minus all the extraneous stuff on the nodes. Any
recommendations or should i just install the laterst version of mandriva on
all of this.

Am researching an 8 port switch. Any experience regarding which brand or
models might be best?
