How do I remove the PSU from Sonata II?

Hi.

The PSU in my Sonata II has given up on life. I want to remove it from the computer myself and send it back under warranty.

What I haven't found in the manuals is how to actually remove it. My biggest question is about the metal bar on the side that helps keep the 5.25s and the PSU in place. There are tiny little holes on the screws/bolts whatever, but I can't make out what tool is needed for unscrewing them.

So my straightforward question is: What tools, size and type, do I need to remove my PSU?

This should be an ATX compatible supply and they are only fastened with four screws from cabinet back side.
You do not need to remove the bars in order to get the supply out.
You might have to remove the fan assembly in order to remove the loosened supply from the inside.

ok, but...

Well I don't see where it could be taken out. I realise the PSU is only fastened with 4 screws at the back, but to get it out of the chassie seems a bit more to it than that. It can't be taken out at the back without bending metal. The PSU seems higher than the space between the top and the side bar. Is it possible to push it forwards and pull it out through the 5.25s? Otherwise I don't see how it can be done...

I'm not near my computer now, as I couldn't use it for obvious reasons, so I can't check on this while reading this...

After removing the fan assembly (dark gray packet) the supply should drop down this way between the bars.

I have an Antec Sonata II case as well and I've had to change the PSU 3 times I think. There was a lot of cursing involved every time, since you have to remove the entire motherboard, alternatively the CPU cooler. Strangely enough Antec still have this stupid bar that is in the way on all the Sonata cases. Why they put it there in the first place is beyond me.

OFF TOPIC: I can mention one really good feature though about the Sonata II though which I'm surprised not to see in any other Antec case - the hard drive bays. Which are located so you can easily remove them without having to take off every side panel in the entire case.
