Design and audience

The Streacom DB4S is a Mini ITX chassis built for silent media-centre or HTPC builds. Its fanless architecture relies on the aluminium side panels to dissipate heat, so it suits users who prioritise zero acoustic output over high-wattage components.

Thermals, noise and power

The 13mm thick extruded aluminium panels act as the primary convection surface, moving heat away from the CPU through copper heat pipes without any fans. Because no active cooling is present, the system runs completely silent, and power draw is limited to the components you install rather than the case itself.

Build integration

The case accepts Mini ITX motherboards and provides two full-height expansion slots for cards up to 200mm long and 116mm tall. Storage capacity includes five 3.5-inch bays and twelve 2.5-inch bays, while front I/O offers two USB 3.0 ports. No power supply is included, so you must source an appropriate unit separately.

Questions about this item

How do I install the motherboard and CPU heat-pipes in this fanless chassis, and what step is often missed?

Mount the Mini ITX board on the universal bracket, fit the re-engineered CPU mount with its copper shim, then route the heat-pipes perpendicular through the bracket into the 13 mm side panels; the step builders skip is tightening the shim evenly so the full copper path contacts the IHS.

What maintenance or replacement will the DB4S need over time?

No moving parts exist inside, so only the thermal interface between CPU shim and heat-pipes may need re-pasting after several years; drive trays and port panels are fixed and require no service.

What physical limit appears first when the case runs sustained loads?

The 13 mm aluminium side panels act as the sole convection surface, so their finite area and 116 mm slot-height restriction on expansion cards cap the total heat the chassis can dissipate silently.
