[kwlug-disc] home voip/backup server recommendations

[Insurance Squared Inc.]

I'm setting up my home office and would like some recommendations in 
terms of hardware for the main 'server'.

I need a box that will be always on as it will handle:
- my offsite webserver backups
- our asterisk phone system
- a small inhouse mysql database.

I've got all this running on two old tanks - server grade machines, hot, 
loud, heavy and indestructible.  But I don't want to run those machines 
in the basement of the house.

Can I get away with an older dell desktop for something like this?  Or 
should I be looking at a tower server?
