I lost my U1 power supply about a month ago, it doesn't even power the 
system on - if you hit the 'on' button from the keyboard, or do the manual 
force-on from the PSU's rocker switch I get a high pitched squeal, the 
fans move for a fraction of a second and that's it.

So, uh.

I thought I'd take a look inside, I can't even figure out how to open the 
PSU! It's clam-shell style, pivots on one of the corners, and I just can't 
figure out what I'm missing to open it. I think I've got all the screws 
out, but it just won't come all the way open and I can't see inside it 
enough to know what it's holding to.

I figure if I can't even open the bugger, my chances of repairing it are 
slim...
