This is an enhanced build based on the Artsy Medical Imaging rig that I posted about 1 month ago. I have customized and 3D printed certain parts to hold the Blue Ray drive, 2 fans and 3 additional PCIe cards.
The build is based on the Intel Core i7 4.2 Quad Core CPU (water cooled) and 2 SLI bridged EVGA Geforce GTX 1080 FTW cards. A 1 TB Samsung 960 Pro M2 drive carries the MacOs and the Plextor M8Pe 1TB PCIe card the Windows OS. A 2TB hybrid drive functions as internal OS mirror disk and an internal 10 TB HDD is for data storage. An external Thunderbolt 16TB Mercury Elite Pro drive serves as an external backup disk.
I have maxed out on ports: Thunderbolt, USB-C, Firewire 400 and 800, USB 3.0 and memory card readers. In order to install 6 PCIe cards, I moved the GTX1080 FTW cards into vertical position using 16x risers. I then 3D printed a PCIe card holder, which I used to install the additional 3 PCIe 1x cards in the Thermaltake case. The fan was moved out of the way into a horizontal position using a 3D printed fan holder. The PCIe 1x slot were split into 3 using the Amfaltec splitter and appropriate riser cables.
