I got PC745, PC746, GK7000 in my hand. they belong to same cpu processor, RAM memory, configure. the only difference is the cabling and outer frame. PC746 fixed with a trail cable with 4COM ports. GK7000 with a clumsy apperance because of battery inside consideration.
The newbie PC765 is interesting, IP64, Cortex-A8... I am exciting to get one.
