The Gigabyte Brix series is the most compact while not losing power. Granted you have to add in your own RAM, HDD, and a OS...... the strongest one is that one there< with a dekstop GTX 760 and i7-4710HQ (low powered quad core). Can use up to 16GB of RAM- officially. Unofficially, with certain sticks, it can use up to 32GB of RAM. Comes with a Gigabit LAN port, a/b/g/n/ac wireless, Bluetooth 4.0, and 2x USB 3.0 ports.
It does that at two point three inches high and five inches wide either way. Wins for being the most compact. However I've heard they are ridiculously loud..so out of the question.
Processor: i5 level
VRAM: 4gb NVIDA GTX 970
(it needs to be top of the line)
Define "top of the line".
Never have heard an i5 referred to as top of the line before. By definition, on the consumer end, i5s are cut down more value oriented i7s. The 970 is also a cut down value 980.
Don't mean that^ as a insult. Am legitimately curious by what you mean by "top of the line".
ethernet (Gig E) (Multiple ethernet? 4 of them?)
Motherboard: Intel z97 based
Can't find regular consumer, or even enthusiast level, boards with 4x gigabit Ethernet ports in a small form factor. All of them are sever boards that cost $$$$ and do not use the z97 chipset but server rated chipsets instead.
The most a consumer board will have is two of them. The GIGABYTE GA-Z97N-WIFI is the only small formatted board I've seen that has two ports. All the other boards I've looked at that have had them are EATX or ATX boards.
Lots of Cooling
manufactured machine is preferable.
top of the line
Manufactured, micro ATX , silent, Lots of Cooling, and powerful do not mix. You will not find a single manufacturer that does all of it. They'll only ever mix up to four at a time 100% guarantee. Silent and slim? sure, but the thing will burn its self up for the sake of silence. Slim and cool? sure, but it's going to be loud. Ok how about silent, slim, and cool? Ok, but all the parts will be underclocked to worthlessness as a set top box.
Pre-built computer makers will do all five, but it's going to cost way more then you're willing to spend. To get everything you want, for the price you want it at, you're either going to have raise the price ceiling or build it yourself.
