I just bought one of these from NewEgg:

I expect it to come in sometime next week, and then I will let you know how quiet/low-powered it is. I already have a Zotac ION-A, and that has worked great for me. I previously had a MSI Wind PC with Atom N270 and a POS Intel chipset, and I couldn't wait to get rid of that system. I was planning on buying a Intel D945GSEJT low profile Atom MB along with a M350 case, but that plan looks like it will die if this Acer AspireRevo does everything the D945GSEJT could do, and more.
