Mainly built from old hardware with the exception of a GTX 1080.
CPU is a Xeon E3-1220v2 with 8GB of DDR3 ECC memory taken from an old server and some blue heatsinks from ebay. Motherboard is ASUS P8H77I. BCLK is at stock and RAM is overclocked mildly to 1400Mhz. The motherboard has a custom white cover on the I/O made out of plexi and white vinyl.
Cooling is built around Eisbaer LT pump/block combo with a 240 radiator and an EK 1080 FE block.
RGB provided by some cheap strips from ebay and a CoolerMaster C10L controller.
Fans are all Akasa slim. One of the radiator fans is connected directly to the GPU via an adapter so it can run independently from CPU depending on the load.
Temperatures are well in check even though the pump is too weak to even push bubbles out of blocks and tubes. Running CPU stress on Linux along with Unigine Superposition gives 65c on all cores and GPU.
