I am considering ordering 20 of those little beauties.

Which powered USB hub should I choose? Preferably ones, which can be shipped to Europe (from Amazon/Ebay). They are going to be controlled by a PC which runs 24/7 anyway.

Would something like this do:

Anker Hubs depicted on this thread:

would probably also do (though I read somewhere that the latest cgminer fails with those)?

What are the USB fans in that picture and are they available in Europe?

If I can't get them, I plan to use something like this for cooling:
