Here is an update:
After struggling with getting Lion installed fresh, using UniBeast, I am now up and running and able to boot from HDD.
@neilhart actually is the first to have gotten this board up and running, and although I have not tested yet, he has practically everything up and running minus sleep/wake. I will conduct further testing myself.
My Hardware:
Viako ML-55 case
Intel DH61AG Thin Mini-ITX board
2GB DDR3 204-pin 1333 Samsung RAM (this will be replaced later, but for the time being, I took these out of my T420S laptop)
19V/4.7A AC Adapter that came with the Viako case
GELID Slim Silence heatsync/fan (28mm tall)
Samsung 3.5" HDD Spinpoint (this will be replace with a notebook HDD on its way and later on down the road hopefully mSATA SSD that will go into the full mPCI-e slot on this mono)
UniBeast USB
Now that I have Lion successfully loaded, I will finish up my build once all parts come in, and will post my build when finished.
