Your system is pre-recovery! You need a 2012 or newer to get the internet recovery service, the 2008 to 2011 system did offer recovery partition services which was a hidden partition on the drive. But if the drive was wiped it likely doesn’t have it. So these options are not available here - Sorry!
Lets backup here … Do we know you have RAM installed? Correct sizes and specs. This system also can only run upto OS-X El Capitan 10.11.6 so make sure you’ve got your drive setup correctly otherwise it won’t boot up correctly.
So the bottom line here is we need to try one more test to see where things are (you don’t need the RAM or a working drive). Restart your system and this time press the T key which is another startup key which will tell your system to go into Target Disk Mode. Your display should show a FireWire icon on the screen. Are you able to get to that point? If you do there’s a chance to get this puppy working if not the logic board has failed.
