I spent the whole day planning my "Dream Machines"... and a few alternate choices.
For those potentially interested in making a bad-ass render-farm rig, here is my shopping-lists. I actually have some of these components. However, this would be my upper and lower limits. I am going to get the "Wet Dream" machine, but without the 1TB M.2 SSD, and with the i9-7900X 10-core, which is only $900. Also, the 1600 watt PSU is already in my possession. Oh, and my single Titan-X will save me another $500 off the price.
Computer #1 (THE WET DREAM MACHINE)
- [$130] RAIJINTEK ASTERION SILVER CLASSIC, an Alu. E-ATX case
- - * {Because this is one of the cheapest and tested cases which fits the E-ATX motherboard and 4x video-cards.}
- [$160] 1600 watt PSU
- - * {Needs 12v for at-least (4x 6-pin), (5x 8-pin), (1x 4-pin), and (1x 4-pin-flat-connector/adapter)}
- [$410] MSI "X299 XPOWER GAMING AC" motherboard
- - * {Needs a CPU with 44 lanes to get PCIe x8/x8/x16/x8, for 4x "Titan-X Maxwells" to run.}
- [$2090] Intel Core i9-7980XE Skylake-X 18-Core 36-Threads
- - * {This has the 44 lanes required for running 4x Titan-X.}
- [$150] CPU liquid-cooler, 3x 120mm fans, 360mm x 120mm radiator.
- - * {Because a liquid-cooler is a requirement for these i9 2066 CPU's}
- [$660] Crucial Technology Ballistix Tactical 64GB (4x 16GB) 3000 MT/S DDR4 SDRAM (PC4-24000)
- - * {Because, why the fuck not!}
- [$2000] 4x Titan-X Maxwells, 12GB each of unified GDDR5 VRAM, non-SLI mode
- - * {For a crazy total of 12288 Cuda-Cores, for rendering. Nothing-else matters but the core-count and VRAM.}
- [$440] Samsung SSD 960 EVO NVMe M.2 1TB
- - * {This is for the greater majority of my 3D content, which I use frequently, and the OS.}
- [$150] 4TB HDD {No specific desired brand. Anything reliable.}
- - * {This is for the archives of additional graphics and 3D content, use a lot less frequently, and swap-files.}
TOTAL DAMAGE: $6190 USD

Computer #2 (THE DAY DREAM MACHINE)
- [$100] Thermaltake Suppressor F51 Power Cover Edition E-ATX Mid Tower
- - * {Because this is the cheapest and tested cases which fits the E-ATX motherboard and 4x video-cards.}
- [$160] 1600 watt PSU
- - * {Needs 12v for at-least (4x 6-pin), (5x 8-pin), (1x 4-pin), and (1x 4-pin-flat-connector/adapter)}
- [$200] MSI "X99A-GODLIKE-GAMING" motherboard
- - * {Needs a CPU with 40 lanes to get PCIe x8/x8/x0/x16/x8, for 4x "Titan-X Maxwells" to run.}
- [$435] Intel Core i7-6850K Broadwell-E 6-Core 12-Threads
- - * {This has the 40 lanes required for running 4x Titan-X.}
- [$110] CPU liquid-cooler, 2x 120mm fans, 240mm x 120mm radiator.
- - * {A liquid-cooler is slight luxury here.}
- [$330] Crucial Technology Ballistix Tactical 32GB (2x 16GB) 3000 MT/S DDR4 SDRAM (PC4-24000)
- - * {Because, why the fuck not!}
- [$2000] 4x Titan-X Maxwells, 12GB each of unified GDDR5 VRAM, non-SLI mode
- - * {For a crazy total of 12288 Cuda-Cores, for rendering. Nothing-else matters but the core-count and VRAM.}
- [$150] 4TB HDD {No specific desired brand. Anything reliable.}
- - * {This is for the archives of additional graphics and 3D content, use a lot less frequently, and swap-files.}
TOTAL DAMAGE: $3485 USD
Honestly, I am not even sure if having 8x PCIe lanes is an actual requirement for rendering. The specs usually dictate "gaming minimums" for "running in SLI", as being some kind of actual minimum requirement. I know all cards can "run" with only 1x lanes. I know, because I ran all eight of my Radeon 7970oc cards on just a 1x PCIe extender and this crappy "i7 4790", for my bitcoin miners. (This CPU only has 16 lanes.) However, I wasn't pushing 12GB of images into each card. I know that 16x is overkill, because the 8x lanes never even get "saturated", (used completely, filled with actual data being transferred).
Better to have them all available, just in-case!
