While shedding some tears over the loss of such a tremendous amount of data on this site, I have decided to do all I can do to restore what's left of it via Google's cache. One of my most extensive threads was concerning the use of a better PSU or secondary PSU to offset the load on the stock SE/30 power supply. This becomes important when adding fast 7200rpm or 10krpm internal hard drives and multiple PDS cards. I will resurrect one of my more detailed posts here...
Here are some photos I shot well over a year ago of my SE/30 setup at that time (click "All Sizes" in Flickr to see larger versions):

You'll find detailed text descriptions for each photo on Flickr. The photos show the insides of my SE/30, the JAMECO PSU driving my hard disk and the Panaflo fan cooling the secondary PSU and the Turbo 040. I put my camera on a tri-pod and did not use a flash so more detail can be seen.
I suspended the secondary PSU between the PDS cards and the yoke with 3 stainless steel L-brackets found at any hardware store. The only modification to my SE/30 case was a couple of drill holes to secure the lower L-bracket. The wood block simply made it easy to mount the brackets and PSU and eliminated worries of shorts. You can see in one of the photos were I tapped the inside of my SONY PSU to feed AC voltage to my secondary PSU.
I also removed the BNC connector on my MacCon card, leaving a gaping hole. Air can flow into the machine through this hole, as well as from the bottom of the case. The Panaflo fan throws air from top down, and the stock fan circulates everything out.
It took a little time, but I don't consider this a serious hack. I tried to make it look nice by covering some of the wiring with corrugate tubing. It took longer to pull the SONY, PSU, open it, solder the AC wires, and close it up than it took to construct the L-bracket mount for the secondary PSU.
