Acer's Aspire U27 all-in-one desktop is liquid-cooled and fanless

I'll admit my bias up front: I think all-in-one PCs typically represent all the worst compromises. It's laptop-ish performance in a desktop form factor, without the upgradeability that a desktop tower offers.
But people buy them anyway, and Acer's new U27 seems like an interesting option. The standout feature is the "LiquidLoop" liquid cooling technology that allows the PC to be fanless. Fan noise can be a real problem for all-in-ones with higher-end specs, so I'm glad to see Acer fighting back.
