Jeff Seal ..just curious, filter cap ratings..temperature
Does anyone else lean towards higher (105% or higher) caps when designing an amp....  
Most of the Sprague Atoms are 65% which really makes me wonder if they're just "underrated" or "overhyped"....(I think I know the answer...) but feel free to share...

[assuming that by "%" you mean "degrees"]  
I've never worried about it at all -- I just try to lay everything out so that heat isn't likely to be an issue.
Book Of The Day The Ultimate Tone, Volume III by Kevin O'Connor
Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn’t change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the “iconic” amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product. Eyelet-board and chassis-mounted tube socket construction is used throughout, for easy servicing and modding. TUT3 is very accessible even if you cannot fully read a schematic and is a "must have" if you are going to build an amp for your self.

Mark's right, an electrolytic cap's life expectancy is directly related to it operating temperature, so don't put them near heat sources. Those ratings are degrees celsisus though, 65ºC is 150ºF, so you don't have to worry about actually destroying the cap unless you play the amp in a sauna or oven ;)

There's nothing like playing in a sauna, IMHO...

Thats true, but playing in an Oven creates this wonderful atmosphere of popping capacitors and sizzling skin that can't be beat! :)
