Would someone be willing to help me setup my server?

Like a real server?

It’s kinda old n shit but it’s got 8tb worth of drives in it 128gb ram 2x Xeon.

It runs but still has something on it with passwords & not sure what I need to do to get rid of that stuff?

Unfortunately i actually need help with this.

Would like in person help.

Would be willing for this to be something that lots can learn from in the local area if possible (Chicago land area).
