Well, there are ALOT of options.. You got 1-wire for temperature.. thenyou use http://www.klein.com/thermd/for the software, get a usb or serial interface device for the sensors, then a couple sensors..http://www.hobby-boards.com/catalog/main_page.php has a good selection.. You can put a good system together for under a 100 i would imagine. Then you've got the ready made systems: http://www.itwatchdogs.com/ http://embeddeddatasystems.com/page/EDS/PROD/HA/HA7Net with http://forums.cacti.net/about13526.html The route I am taking is the 1-wire one, so I dont have alot of information ont he others.. the Ha7 product is just a ethernet device for the 1-wire interface. It communicates to the Cacti install of the monitoring server.
