HDPlex is teasing HTPC builders with an updated version of its H5.S ATX fanless case. Yes, you read that right—"ATX fanless." The case itself looks like a big radiator, and it comes with a heatsink and heatpipe set that supports CPUs with up to 95W TDPs. A similar heatsink arrangement is available for the GPU as an option. With the optional GPU heatsink installed, the company claims the case is the world's first 16-heatpipe fanless chassis. FanlessTech has some exclusive pictures of the sleek beast.
The H5.S is compatible with ATX, microATX and Mini-ITX motherboards, and SFX or Flex ATX PSUs. As an additional option, users can feed power into the case via an external ATX connector. Graphics cards are installed horizontally using a PCIe extension cable to make way for the optional heatsink and pipe set. Only two PCIe brackets are available, which is arguably more than enough for HTPC purposes.
Builders can slip in a 5.25" optical drive, and the case has enough room for up to three 3.5" spinners and six 2.5" drives. The chassis is 16.9" (430 mm) wide, which matches the standard AV rack width. If you're concerned about whether the case can take the heat, an HDPlex employee posted some numbers in an official forum thread, and they allude to GPU temperatures under 70° C while gaming with a GeForce GTX 750 Ti and a Core i7 4770K.
HDPlex says the H5.2 chassis is in the "tooling phase." Once it's done, it'll be available for $275, in either black or silver brushed aluminum finishes.
