I still want one of these things. When I mock up my small house floorpland, under-stairs/loft desk area, etc., I've changed my computer from the 21.5" iMac to this new 24" model. Not much difference, side-to-side, actually. Just a thinner body, viewed from above (I did have to Google what 11.5mm translated to in inches).
FWIW, the 21.5" iMac has been the placeholder Mac/dimensions that I've based any desk/nook around for several years. Something came along and made me re-draw that part.
