Today we had a power outage in my area. As a result my two computers lost power (yes I know I should get a UPS). One of them restarted fine and the other, a Shuttle XPC Model S141H, will not boot. When power is plugged in I can see a yellow and orange diodes come on through the grill but when pressing the power button nothing happens.
Ideas for getting this going again?
What should I look for if I open the case?
EDIT: There is no warranty left on this computer – thanks for the reminder though. I put it together from all new parts purchased about 2 years ago.
EDIT2: Here is a photo of the computer with the case off. When I plug in the power those 2 diodes are not illuminated. When I hit the power button the 2 diodes (I assume that they're diodes) light up but nothing else starts.

Before you start swapping parts out to test, I would first try clearing the CMOS. It's possible the power outage corrupted some of the CMOS/BIOS settings. It should look like the following picture, or you can consult documentation on your Shuttle PC.
To reset it, find the jumper, which is normally close to the battery. It has three pins; the jumper will be on two of them. Move it over one so it is now covering the pin that was not covered to start. I like to pop the CMOS battery out just to make sure it resets. Wait 30 seconds, then put the jumper back the way you found it and pop the battery back in.
If it works, your PC will start. You should go in to your BIOS to confirm the settings. Most newer BIOSs will detect the proper settings automatically, but still ask you to go in and save/exit.
If you have a warranty on the PC, opening the case may void it. I would check with Shuttle on that.
If this doesn't work for you, then you have to start swapping out the power supply with a known good one to see if that's the problem. For example, you could try using the other computer's power supply, since you know it works.
At this point, I would suggest taking it in to be looked at, unless you really want to test it yourself.
