I am in the process of building a really nice new PC right now. It's going to have a nice Lian Li case with the internals powder coated black and all the wires will be sleeved. So my problem is I am getting parts in a couple days but my case will not be completed for about a month because it is on back order plus time to powder coat it. I am purchasing many of m y parts from newegg.com and they claim you must return any dead parts within 30 days or the invoice for there warranty to replace bad parts.

So is it possible for me to set up the PC without a case just to test that the main parts are working correctly within the timeframe I am allowed?

If this is possible, how do I deal with turning the system on/off without a powere button? Or is therer one on a motherboard? Thanks for any tips/advice
