home theater PCs, size matters -- and it doesn't get too much smaller than Sapphire's original Edge HD mini PC, pictured above. In fact, Sapphire saw no reason to fiddle with the Edge's diminutive form factor when designing the HD2, and instead poured itself into improving the HTPC's specs. Not only is the updated mini-rig small enough to mount behind your HDTV, but it also packs a 1.8GHz dual-core Intel Atom, 2GB RAM, and a 320GB hard drive. All this (and 1080p VGA / HDMI out, of course) at 30W, "20 times less power than a typical desktop PC," according to Sapphire. No word on price (or pics, for that matter), but feel free to jump past the break for an official press release with full specifications.
