I found a mod a couple of days ago where someone made a chassis intrussion detection switch or something like that and wanted the link for it as i have lost it. thanks guys

Some cases have a case switch which is connected to a mobo. It beeps if the case is opened. Nothing special.

its somethin pretty special when u go to a big lan

im sure you could mod something up pretty easy since radioshack sells the parts for em... take a look =)
