Interesting, though the side panel window in the top picture appears to be simply nailed onto a hole rather than the perspex being built into the panel itself...can't say I particularly like that. But they do offer a version with sound dampened panels...sort of like a very expensive, stylized R3 (and at £100+ I'm not kidding about expensive)
Unfortunately the only place I can find that sells it is Casekings and I can only find one or two reviews of it in English, but they are relatively positive.
