Working on a idea where I install into my new case a backup power supply so if say you kick out the plug the system can still run, much like laptops do when unplugged
Found this http://www.bixnet.com/unpowbat.html
and they are even designed in a way you can daisly chain them together and what i was thinking was to daisy 3 of them together and tie it together with the PSU plug so you only need one plug but when plugged in it charges the battery and powers the PSU. While in theory i could just have the PSU and Battery pack use a surge protector strip if you unplug the Surge protector it's going to die, i need to find some way to route the PSU power through the battery and then charge the battery from the plug but i'm not sure just how to pull that off. Any Ideas?
Charging the battery pack isn't the hard part (you could hook the 12V rail from the power supply to the battery pack), powering your system from the battery pack is. To power the system from the battery, you'd either have to convert the battery output to 120 V AC; or convert the output to 5V, 3.3V, etc. and hook them up to each rail of the power supply output.
I'd suggest using dual power supplies, an external backup power supply, and/or just be careful to not unplug your system.
