Design and spec all components for Deep Learning Workstation Server with OS installation

I am looking for a computer hardware expert to design and spec a parts list for a rack mount server build. I am looking to build a a deep learning server for personal use. Parts that you will need to spec for my build. 1. Motherboard (Must support 4 gpus) 2. CPU. 3. Server case and cooling fans 4. Hard drives. 5. Power supply and all cables required. I plan on using 4 Gpus and 1 processor, with 3 hard drives and multiple ram sticks. I will provide the list of parts that I already have. I will need the server case to be spec'd for the build. As well as detailed written instruction on how to build it. The server case must be able to fit the 4 gpus and they should be cooled efficiently. I will also need the OS to be installed for me. I can do this myself if written instruction is provided. If teamviewer/video call is an option then this will be better for me. Feel free to contact me and I will specify which parts I already have on hand.
