How about we fork this in to a several different competitions:
1. FPS per liter. For gaming machines. Where not the number of cores but the "per core frequency" is important.
2. Storage and streaming capacity per liter. For NAS that can do streaming (Plex, Emby). There can be a lot of fun with...
no, it won't be. Because the PCIe x16 slot is pointing to the side AND the cable is too long.
In Gallon case the riser cable is attached to the chassis and play an important role in supporting the GPU. So it has to be the straight type.
No. The CPU cooling I have Zalman CNPS2X, can not work in reverse. v3 will have space for NH-L9...
Nope - think of the other hot things around the CPU, like VRM, NVMe etc. They need cooling too. And the outside air is cooler.
Role of the holes = The back of the MB needs some cooling too. +...
;) We 'll see.
I have Creality CR-10. It currently cost about 300 EUR. Check youtube reviews. That should help you make your choice.
As for compatibility - do not worry. The 3D printers are still so stupid, there is no way to limit them to a OS. 'cos they have no drivers.
I am not familiar with the Italian market, but you can chose one from here:
Still I will recommend buying a 3D printer:
or if I have to recommend a brand:
HDPlex 400W will not work in this case. The FlexATX PSU is an integral part of the case. It gives rigidity(it holds the sides together) and stability(lowers the center of mass) to the structure.
The FSP400-60FGGBA FlexATX PSU I linked is working perfectly for me for 19 months already. It is...
The eGPU from the link above, has a mini PCIe. This means PCIe x1. That is really slow on the texture transfer.
The number of power bricks should match the number of cases. If the eGPU and MB/CPU/RAM/SSD are in separate boxes, then go for separate PSU bricks.
You mentioned you want to travel with that PC. That makes weight and volume important. To minimize those two I would recommend:
1. Go for 65W TDP CPU. CPU cooling will be shorter (e.g. nh-l9a) that reduces overal case volume/weight.
2. Go for nVidia 10 series. Currently 20 series are not...
