Well, I have some updates:
First off, from what I can tell, the CN13000G is physically setup different the other VIA Mini-ITX boards. That makes it a tighter fit into the VoomPC2 case. Specifically the power connector to the motherboard and the placement of the IDE connectors. After some test fits, and buying a shorty IDE cable, I am pretty confident it will stand the test of time. Will upload some pics of what Im talking about later.
Second, I bought some DDRII533 for this install - Kingston KVR533D2N4. Well, that doesnt boot, but I went locally and found very similar RAM - Kingston KVR533D2, and it booted right up.
Here it is hooked up in the house, getting ready to install nLiteXP:
Should be in by tonight.
