HFX Fanless Monster PC

Monster PC

With the know how we have gained as leaders in the quiet computing market, our Fanless HFX Monster PC is the most unique, full-functioning, and absolutely silent (fanless) PC available.

Intel Z97 ChipsetCompletely Fanless This HFX Monster PC is completely fanless...from CPU cooling, to video cooling, to fanless power supply, to fanless motherboard; every component is carefully matched together to provide a stable, seamless, and powerful experience without any fans. The HFX Monster case itself is a massive, ridged heatsink, that takes the heat from your primary components and routes it through heatpipes to the outer chassis.

The HFX Monster allows for the use of any standard ATX power supply for maximum power, resulting in a real monster PC of a fanless build. We have paired the Silverstone 520 Watt Fanless Power Supply with the HFX Monster Case for ultimate fanless performance. For maximum silence, we recommend a solid state hard drive as an option for your system.

Truth be told, the HFX Monster is completely unique fanless build. Its solid case is as heavy duty as it comes (this is no lightweight case). It's large enough to allow for ample cooling of numerous components. The Monster's case has room for up to 6x Expansion Slots and 6x 3.5" or 2.5" Drive Capacity, allowing it's ownder to take full advantage of your motherboard options. Additionally, the HFX Monster can passively cool an add-on video card, with unique video heatpipe cooling.
