Need to fix home-made server blunder

I think I made an amateur's mistake. After building the machine here:

I used the "cheaters method" explained in the link ("- Cheat -> Heatsink -> 'Meat' -> CEK Spring ->
Nuts that fit the screws") but did NOT use the kit or backplate mentioned. As a result, the CEK springs touch the chassis of the case. Then I plugged in power to the power supply. I suspect I shorted something out because initially the CPU fans would turn (no POST beep though) but now the motherboard won't power on. The power supply did smell a little funny but not like smoke. I need to get the server running. Any thoughts on how to proceed?

You might have fried the board or power supply.
I would get a known good power supply and test the server after making the following change.

put plastic washers on bottem of the mainboard just before you put the nuts on also get a small can of liquid platic dip and a dip the nut in it and take a smal brush and coat the bottem of the bolts.

ComputerTechie is right.  There may be damage to either the board or the PS.

I'd start by extracting the motherboard from the case, put it on a chunk of cardboard, and see if it powers up out of the case.  If it does, no hurt no foul, both motherboard and power supply are OK, reinstall them according to his instructions.  I'd use nylon washers, bolts and nuts in this situation, available at any hardware store in the random-hardware bins.

If the motherboard won't power up out of the case with the original supply, then continue with a known good power supply.  If it powers up, the power supply was damaged; if not, the motherboard was damaged.

So were you able to save the mainboard ?

I thought I'd open another question, but my biggest concern is how to attach the nuts (with a nylon washer between) to the spring-screws of the heat sink with motherboard between, since the fit is already extremely tight (image: http://cgi.ebay.com/ws/eBayISAPI.dll?VISuperSize&item=150328124127). Is there something like an "extension?" for the spring-screw? Again, configuration is: Heatsink -> CPU -> CEK Spring -> Nuts that fit the screws"
