Just pull everything off the mobo except the cpu, fan, memory and video card. Make sure the front panel connectors are in the correct places. power up the board and see if you get the cmos load up. Relax....take it one step at a time. add the hard drive and attempt to install the os. If you get that far just start adding things one at a time. Smoke doesn't necessarily mean "death" but it is not a good sign!
