Building Octane Machine - Advice

[HyperNerd]

Hello,

Mac guy here looking into building a PC workstation specifically for Octane. I'll primarily be using C4D/Octane and building around 4 GPUs. Looking for advice on some configurations I'm considering...

I'm leaning toward this overclocked gaming PC from MAINGEAR with the following stats:
MAINGEAR FORCE X99
• Motherboard: ASUS RAMPAGE V EDITION 10
• Processor: Intel® Core i7 6900K 8-core 3.2GHz/3.7GHz Turbo 20MB L3 Cache
• Memory: 32GB HyperX® PredatorT DDR4- 3000(4x8GB) [QUAD Channel]
• Graphics Card: QUAD NVIDIA GeForce GTX 1080 8GB GDDR5x
• GPU Liquid Cooling: Quad Card EK Supremacy - Nickel
• Power Supply: 1500 Watt Corsair® AX1500i 80+ Titanium Modular PSU

Note the liquid-cooled quad GTX 1080's in this i7 machine. Thoughts? I'm quoted around $9500

Also considering a similar build, but with a dual Xeon's instead. The difference being it will not be liquid-cooled. I'm assuming that would make for a hot and loud machine?

As stated, I'm a long-time Mac user, so this is new territory for me. Thank in advance for any input!

4x 1080 on water and much better mobo (4 gpus at x16) fully watercooled withj Aquaero shall be around 6000EUR net ( 0 VAT if you have business). PM me and look at my posts.
