Okay, I'll take a stab...
Is this the
right manual?
Does absolutely nothing happen when it's powered up (you mentioned the case has pretty lights
)? I mean, if the ps if fine and the motherboard is properly spaced (and worked before, right?) then it has to a be wiring problem? I would double check all the connections made from the case to the mobo. From personal experience...I once had to use an error riddled manual and mixed up a couple of the connectors and the thing wouldn't come on at all.
So, if the link I posted is correct, I would just run through and double check everything as there's a good chance you mixed something up what with using the wrong manual and all.
Good luck.
