One special thing: Intel Quick Sync Video. It's the dedicated video encoder/decoder part of the CPU, and seems to be one component cut in Celerons. Though I saw some report variants of the Celerons having just the decoder.

If the software stack takes advantage of either the encoder or decoder on the CPU, it would probably work fine, with plenty of raw CPU power available for whatever else. Pretty sure WMC does. Not sure how support is on Linux though, one hurdle for usage was removed back in January.
