FanlessTech published a preview of the updated H5 case from HDPLEX, which accepts CPUs that are up to 90W TDP. That is a lot of potential performance for a silent device, especially since it includes an optional fanless heatsink for dual-slot graphics cards. That said, because the company creates home theater PCs (HTPCs), they have a reasonable amount of room to work with, unlike a NUC (or similar) form factor. It keeps the components cool by attaching them to the case itself with heat pipes, using its mass and surface area as a reservoir and radiator to keep the heat away. The CPU and GPU each have access to eight pipes, sixteen total.

Beyond the home theater application, I can see this being useful for many professionals, especially sound engineers, who want a lot of performance but no noise. And even though it is not tiny, it is not even a foot and a half at its largest dimension, so it should not be too difficult to find room for it in a cabinet or something. Also, just to put the 90W TDP into perspective, Devil's Canyon is listed at an 88W TDP. You could probably fit one of those in here, although non-trivial overclocking is likely out of the question.

So yeah, fanless Devil's Canyon with options for a fanless discrete GPU. I think I made my point.

This photo is from the previous model. The upcoming chassis is not yet pictured.

The final design is not yet published, which is why we included the picture of its previous incarnation, but HDPLEX claims that production is currently in the tooling phase. Despite not yet being available, it is listed to sell for $275 USD. If the previous design is any indication, it is quite stylish too. It could pass for a retail BluRay player if people don't stop and wonder why there isn't a brand logo on the front.
