I'm still deliberating between three options and considering some of their minor differences to make a choice, taking the opportunity to bump this thread up and also post those differences:
- X10SDV-4C-TLN4F // D-1518 / 35W TDP / 10GbE: Yes / 4C 8T/ 2.2 GHz / 808,03€
- X10SDV-6C-TLN4F // D-1528 / 35W TDP / 10GbE: Yes / 6C 12T/ 1.9 GHz / 1.058,96€
- X10SDV-F // D-1541 / 45W TDP / 10GbE: No / 8C 16T / 2.1 GHz / 499,00€
I'm choosing one of these because the processors they allow (and come with soldered and preinstalled with) seem to be a good balance of performance, power consumption and heat generation, specially considering the limitations in space and cooling set by the Jonsbo N2 case.
The second hand X10SDV-F wins when it comes to processor performance and price, but loses when it comes to power consumption (marginally perhaps) and the lack of 10GbE (although that's not a strong point at the moment for me anymore since I'm planning on possibly adding an SFP+ card to whichever mobo I buy).
The X10SDV-4C-TLN4F seems like the moderate choice if I'm buying new and want to limit power consumption, with a good CPU only slightly worse than both other options... but maybe at that point the X10SDV-6C-TLN4F is worth it for the extra CPU performance?... Although It seems like the base frequency of the processor is low, I'm not very savvy when it comes to hardware, but I think that's not a good thing(?)
Any thoughts or comments on what I said, to help me decide, would be greatly appreciated.
