I plan to install later a linear PSU inside the large black case but need to leave space for adding a 2nd 3.5" 2T HDD in future. Can a R-core transformer with enough power [60VA?] plus other parts [rectifier diodes, capacitors, etc] fit in the case?
You mentioned that part of the 12V has to be converted to 5V for certain components inside the server. Can I build a linear PSU with both 12V & 5V for direct connection with better sound?
I have a SMPS 12V 3A & another linear PSU 12v 3A. Can any of these be used for initial testing?
I confirm to use my own external linear PSU 3A 12V [adjustable from about 10V to 18V]. In case of need, I can build another one with 4A or more. So, I don't need the SMPS. Tks.
