Well those suggestions were just an example for going as cheap as possible based on US prices. There are certainly better motherboards. Ideally I would recommend a full ATX board with crossfire capability along with USB 3.0 and SATA 6 g/s but that will likely cost at least twice as much. As for the processor like I said earlier the unlocked multipliers on the black edition chips isn't too big of a deal. Unlocked multipliers are nice but I wouldn't make it a big priority when deciding.
As for the different brands of the HD6950 all of the cards available right now are the reference model and basically identical. So decide based on other factors like price and warranty. All of them use a dual slot cooler which will cover the slot below the PCI-E x16 port. For example on the board I linked one of the PCI slots would be covered but you would still have the other one available along with the PCI-E x1 slot when the card is installed.
