I am planning on making an order for caps and notice a lot of them have -40 celsius to +85 celsius on them and some have a 105 celsius temp. Should I stick with what is on the individual cap or go with the higher temp rating?
Thanks in advance!
 
You can always go higher on the temperature rating. The 105 degree parts tend to be higher quality and last longer, but they're slightly more expensive. I usually only buy 105's unless there is a real reason not to - and when you buy them in bulk the price difference isn't quite as bad.

Also, you can always go higher in voltage rating.

I agree with everything Ian said. Remember that higher voltage caps will generally be physically larger in diameter and overall size, and you can run into problems fitting the larger/higher value replacements on a board. You won't see this as much on monitors (usually), but will see it in certain power supplies and other projects.

These are mainly for monitor chassi. Thanks for the input!
 
One other stat I find important with caps is the Lifetime that's associated with the temperature. This is how long the cap can sustain the maximum temperatures (theoretically).
