I have the following switches that are fully functional but collecting dust: Dell PowerConnect 3248 (48 port 10/100 switch) 3Com Switch 4400 3C17204 (48 port 10/100 switch) 3Com SuperStack 3 Switch 4250T 3C17302 (48 port 10/100 switch) I just connected them and they work fine. Are they worth the electricity that they're running on? I'd love to set up some sort of a home lab either tied in or separate from my home network. I don't have a rack but I wouldn't mind buying a wall-mounted 6U or 8U or 10U or 12U rack. Thanks for any advice!
