case style / format?

[MagnusTheBrewer]

Sorry if it's a silly question but, is there a name for the style or format of a case where the MB faces up rather than being mounted on the sidewall?
That's horizontal for the visual relationship challenged.

Traditionally it would be a 'desktop' case (i.e. the old IBM days) but nowadays would be called a media case or HTPC case. The difference being the 'desktop' case lays horizontally, the 'tower' case is vertical.
