Better part suggestion would be appreciated.
Good build, why mini itx?
it's going to be my first build and I like how the prodigy looks. Would it be better to go for a mid-tower?
Mini ITX is fine as long as you've done your research into it.
It looks good so far. If you want cable management to be much easier, consider a (semi)modular PSU. They're a little more expensive, but they will save you from dealing with the unnecessary cables.
I've research this case and most places recommend a non modular because of how the wires come out of the power supply.
