Built by Enthusiasts.
I've built hundreds of systems, and this is my go-to for clients who need silence without sacrificing wattage. The modular cables are a dream to work with, and I literally cannot hear it running in a closed case.
Running dual GPUs for rendering, I needed something that wouldn't add to the thermal or acoustic load of my studio. Three months in, the fan hasn't even spun up audibly once during normal workloads.
