The closest thing I know to do (what I just did building my new system - my first) is what someone recommended to me. Do an out of the case test so you don't have to mount the mobo and then unmount it if it doesn't work. Put the mobo on an antistatic surface (I used the antistatic bag it came in on my desk). Throw the cpu and heatsink on the mobo (not that hard), a stick of memory & video card (if you put the mobo on the mobo box you can hang the vid card over the edge) & hook up monitor. Hook up the psu & front panel case connectors to the mobo & turn it on. It should spin up the cpu fan & boot to the bios screen.
If you don't have a cpu handy I think you're SOL.
Hope this helps
