Asrock no longer holds the title of "cheapest P55 mobo manufacturer ever." This honor now belongs to ECS, with its new P55H-CM motherboard, now available for the low low price of just 4,780 Pesos. That's even cheaper than some LGA 775 and AM3 motherboards out there. Doubts about quality aside, the ECS P55H-CM motherboard comes with four 240-pin DDR3 DIMM sockets that support up to 16GB of memory, one x PCI Express x16 slot, two PCI Express x1 slots and 1 PCI slot. It's built in a Micro-ATX form factor, which would make it perfect for use in SFFs and HTPCs. It might be a good idea to wait out for reviews of this mobo before going for it, though.
