Those links don't work and I for one wouldn't have wanted to press them all. I and others find it helpful if people post descriptions or model numbers next to links.
If you do this and fix these links then I will be glad to come back and give my opinion.
It is possible to SLI GTX 560 Tis with 650W PSUs, but it would be more "comfortable" with a 750W unit. The Corsair 750TXV2 is a good choice.
As you said that you want to overclock I think you should consider getting an aftermarket CPU cooler, which will help keep both the temps and the noise down compared to stock.
The Cooler Master Hyper 212 Plus/Evo are popular budget choices. The Evo is the update of the Plus, the differences include an improved base, lighter weight, and a fan that is, according to the specs, quieter at the slowest speed, but noisier at the highest speed. I would suggest making a different choice if you especially want the noise level to be low, or at least changing the fan.
The Plus/Evo are unlikely to interfere with RAM slots, but there are coolers around which would prevent you from using them with RAM with tall heatspreaders like the Vengeance, especially if you wanted to fill all four slots.
Tall heatspreaders are mostly unnecessary these days (perhaps unless you wish to heavily overclock the RAM itself) so if you do decide you are going to install a CPU cooler (now or in the future) then if I was you I'd try and get a set without such tall heatspreaders - Corsair sell Low Profile versions of the Vengeance for instance.
