The title says it all. I'm considering to buy a new computer, maybe a Xeon e3-1246 v3 (it can also be an AMD or a i5, i7). I want to have lxc containers and virtual machines and want to have my data as safe as possible. But I'l like to have this as cheap as possible, although with solid components.

So, what motherboards can suit me? There are workstation motherboards for Asus, for example, but they are expensive. I've also read some good things about Asrock regarding IOMMU support.
