Thanks guys - I've tried Hulu on an Atom processor in the past and it's complete failure, just shows how weak those things are. I was just mainly concerned because Hulu lists having a Core2Duo as recommended specs, which seemed oddly high to me.
So, I'm looking to build a pretty low-end HTPC. I don't have a HDTV yet, so I'm likely to use the box with either my 30" LCD or via S-VIDEO on a big old rear-projection TV.
I've got just about everything figured out - but my main concern is Hulu. I know Flash doesn't yet seem to support...
