There's no obvious way to turn it on. It's not in a case I know, I'm working on that but there's no front panel connectors to even connect a power switch to.
It will also run off my old PSU which is ATX. Which turns itself on and off electronically, not with a huge hefty switch, like this one.
What do I do? Will it work? How do I turn it on? It it worth putting XP on it (18gb hard drive), CPU: ??? RAM: ???
Any help will be greatly appreciated!
