Sega Dreamcast
From Sega Retro
Something that may need clarifying at a later date:
Dreamcasts have a triangle at the front of the unit, part of it is an LED which lights up when the power is on. The other part, which is placed on the lid, varies in colour between regions. In North America and PAL regions, it's grey. In Japan... apparently it's a transparent piece of plastic. This isn't overly obvious in photos, and I'm not sure exactly which models it applies to, but it's the only obvious distinction between North American and Japanese models when the unit is photoed from the front. -Black Squirrel 12:38, 30 January 2011 (CST)
