I'm jealous, wanted an H2 as well but was out of stock. Will probably get one when they are available again. Interested to hear what you think of it so far.
I'm really happy with my H2.
You can check the odroid forum sometimes some users sell there H2 for a reasonable price.
That's where i get mine too i was lucky i guess.
A while ago in installed 5schatten his build and it was running great almost all emulators that i tried are playable except PCSX2 is not but that was what i expected.
Soon i'll try your build but i really don't know what the difference is between your build and 5schatten his build.
