because its an off the shelf computer.
Here's a few pictures.
The one i currently have is non-modular i think. would that make a difference with respect to wires to the rest of the case?
And do i simply disconnect the wires coming from my current psu to the other parts of the computer? Sorry but i'm clueless when it comes to things like these.
I don't think a modular psu would fit in my current computer.
