My current setup for the weather station is a dedicated IBM PC350.
Web server runs very slow when everything is running at once.
I'm building the system myself with a few new parts like the case, processor, motherboard and ram, and some parts I already have, like harddives, cd-rom zip, network card, etc. Sometimes I use this PC additional for Outlook and Internet Explorer. No mayor problems with the network. 30 gig Drive. External USB to my color printer, Palm hot sync, scanner .
