I'm once again here for your help.
The problem is quite simple, i'm having some hard times in powering on my Desktop PC.
Basically, i push the power on button and it doesn't fire. After a while i try, it starts.
The last time i've disconnected ethernet, all external HDD, and flipped a bit with the PSU switch.
This time i've disconnected ethernet, flipped once PSU switch, and after about 20s i was pressing the power on key, it worked.
The external HDD and the LED on the mouse do work once they're plugged, even if the PC is off, so i know there is power there.
Knowing this, my 3 suspects are: MOBO, PSU, CASE.
The case is a Thermaltake Versa H21 (so you could say a cheap one...)
The PSU is also a Thermaltake: https://www.amazon.it/gp/product/B004YISIB2/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
Here is my hardware
I guess i could unplug the PSU and use another mobo to find out if it immediatly turns on, but i'd have some hard times in testing if the fault is in the MOBO or the Case. I've no case in which all of this could fit and i've got no compatible PSU with the system.
Another reason why i believe it to be the Case is that once it powers, i've got no problem, even leaving it on for a week straight... I guess if it would be a failing PSU or mobo i would have some other problems.
