XBMC forum member aicjofs tore down his Apple TV while waiting for a jailbreak and discovered the unit has 512 MB of RAM and 8 GB of on-board storage. It also has a dual-core A5 processor identified as APL2498, which suggests it is a variant of the standard A5 found in the iPad 2. There's also a second antenna whose purpose is unknown. You can check out all the internal eye candy at the XBMC forum thread.
