Team Render in Cinema 4d does not use Thunderbolt, it uses Ethernet.
You already have the ability to render to other computers by installing the Team Render Client on any computer you want to use on the render farm.

A homebuilt PC will be the best bang for the buck in comparison to the MacPro, iMac or MacMini. The iMac and MacMini just don't have the kind of thermal characteristics you'd want for a render slave. The MacPro is just too expensive compared to a PC. My 4930k runs at 4GHz so it's faster than my nMP 6c and cost about half as much.
+1 Coolness/temps really matter much when rendering for long durations.
A 4c i7 with a cheap motherboard will be the cheapest and a good bang for the buck. When you get into 6c or higher, you start to need more expensive motherboards, so, do the math on what works best for you.
I consider the Gigabyte UP4 ("GUP4") to be a cheap motherboard - It costs under $250. I've got eight systems using them and those systems have 6- and 8-core processors. Moreover, my experience with them is such that I wouldn't hesitate to put a 10-, 12- +-core CPU in a GUP4. Plus C4D really rocks with Nvidia CUDA/GTX GPU enabled rendering, especially since the Team Render feature was added. I use both OctaneRender and TheaRender for GPU rendering (and soon hope to test FurryBall for C4D; additionally, RedShiftRender is said to be extending to C4D). The GUP4 can handle up to four double wide GPUs. I highly recommend the SilverStone Raven case. This case is cool in more ways than one. Innovatively, the case flips what is traditionally the front and rear of other cases 45 degrees so that the intake fan, which now really cools the motherboard and attached GPU(s), are at the bottom of the case and the GPUs now exhaust immediately from the top of the case. Your four GUPs can hang like this: I I I I

The Raven is thermally sound and makes me ask myself why wasn't this the case design orientation originally used as the standard by other manufacturers when multi-video card systems began to become more common. Excluding server cases, the traditional case design is brain dead stupid for multi-video card systems. In a multi-GPU case configuration, the GPU farthest from the CPU is the coolest, but it heats the one on top of it -> making that GPU hotter and the one that gets heated even more heats the one on top of it etc etc ->the top most GPU being the hottest and to make matters even worse, it's the GPU now closest to the CPU.

I suspect two 6c computers would be cheaper than three 4c computers though when you factor in RAM, cases, boot drive, and Windows licences. They have a Linux client but only make it available to the big boys. Really (really) wish they'd release a Linux client for the rest of us.
+1 Excellent observations.
My C4d "render farm" is a nMP 6c, 4930k 6c, 3770k 4c. All Intel, all Ivy Bridge. Don't think the Sandy Bridge/Ivy Bridge/Haswell part matters, but I have heard it is best to stay on the same processor manufacturer (AMD or Intel) although I have no first hand experience in a mixed environment. The Windows and Mac computers all play nice together.
+1 I tried a mix of AMD and Intel systems and it was a nightmare. Apples (hardware-wise) are really Intels, so I've had no problem mixing them for GPU rendering (But, see preceding post regarding V-Ray).
The Mac client for Windows RDP is indeed good.

Also the licenses differ. I use C4d Broadcast, so I think I'm capped at 3 clients.
I'm not familiar with the Broadcast license.
P.S. One can even use very old MacPros (I use my three 2007 MacPro2,1s) in a GPU rendering network. With a little creativity, one can load up to three double wide GTX GPUs in them [
https://forums.macrumors.com/showthread.php?p=18887887&3+double+wide+gpus#post18887887 ]. They're not as cost effective as an external chassis because of GPU rendering software licensing methods and costs, but an old MacPros provides you with another full system and may actually dispense with some of the issues that I've read about recently that others have encountered when working with an external chassis.
