Very useful design. Too pricey. Some considerations about the case's cooling properties:
Case cannot be kept in a cabinet enclosure, and under a desk is worse than beside a desk. Some people have thought to throw a room-fan on the case to facilitate heat-dissipation.
Despite a longstanding argument with a friend who made his own choice of CPU coolers, there is enough review data from controlled test-beds available to pretty much prove that heatpipes "work". It would be nice if somebody like Zalman could provide "heat-pipe kits" that can be applied to any case, be it aluminum or steel, old or new, midtower or full-tower, but I suspect the manufacturing costs might be prohibitive and if not that, then there is the problem of how you make the same pipe assemblies and heatsinks fit different case models.
I'd be willing to spend maybe $100 or even as much as $150 (depending on accessory features) on such a heatpipe kit to use in a case-mod. You could then augment the heatpipe cooling with fans and exhaust ports-- still using a fraction of the number of fans that many air-cooled systems provide without exotic cooling innovations.
But steel cases do not have the "heatsink" capabilities of aluminum cases.
