Audiophile grade computer?

[joes1234]

I want to eliminate as much noise that could be added during playback.

 

I intend to play my files (WAV. ripped directly from my CD's)  from my Laptop.

DELL Inspirion 15 7000 gaming, 

It has no fans just thermal cooling, so hopefully no extraneous noise.

and directly connect it to my Oppo UDP-205 as a DAC and then to my stereo.

I am including a pic of the 205's rear sockets.

I intend to use the USB DAC input.

Cardas clear serial bus wires.

 

 

My question is;

1) What is considered an audiophile grade computer?

2) Will the dac clean out any added noise if there is any from the computer?

3) Is the connecting USB wire a consideration?
