Hi flmaxey
Thank you for your answer. The purpose of the virtual machine is to have a machine always on, justo for me to connect to it from outside. Like establishing a vpn and then connect to it using RDP. This machine will be windows 10 and as i said is to have a available machine to do some browsing open some files, run some basic tools and nothing more, it will perform like a desktop. Another virtual machine is a linux to have the same purpose, this is just for lab testing and nothing more.
So, this linux machine will not be always started, and can be shutdown.
For what i have investigated, the 4000 series intel cpu was a great choice, it will speed up the TDP to a higher value. This will be a problem for me because i have a Fractal cube already with 6 Sata disks. The second problem is the higher value of the 4th generation cpu. This option is the best for me, but i dont know if its the best. Compare it to a I3 8th generation that have 4 cores. The used i5 price is higher. The problem with this option is that i will need to buy a new board, New CPU and new memory, the advantage is that i have a lower TDP for that.
These were my choices, but dont know what is the best one.
