I had to buy a new power supply for an old case recently, but when I went to install it, I realized that it was smaller than the previous one. I was able to mount it on one side with two screws, but it wasn't really stable. It took a phone call to Antec to find what I needed, and even knowing what's on the page, I can't find it with Google, so here it is: Antec Power Supply Mounting Bracket Hopefully that'll save someone else the trouble I went through. ADDENDUM: The commentor is correct. It has been moved. If you call Antec and find the new location please post it here.
