It depends very much on what your needs are, whether you would
leave machines on overnight, etc.
If you're happy enough leaving a single machine on continually,
juct locking/blanking the screen & coming back to whatever you
were doing later then you have a perfect case to hang the modem
off the back of that machine and make it your 'server', and to
have a second machine for everything up to 'crash and burn'
testing ("Oh its trashed my disks.. well I'm annoyed, but
then again its not my server" :)
You seem to be pretty much on track :)
