Starting with a more simple mod

[djsv103]

So I got my second phat and imma give it a clear ring. But im gonna use a psp faceplate's screen to make the ring.

And heres what everyone has been waiting for the questions(you thought i was gonna say pictures).

Where is best to buy LEDs and wire?
Whats the best amount of LEDs to go with this mod(i was thinking one in each corner)?
If i put LEDs in it will i still have function of my UMD tray?

I will update with pictures once it is done so dont worry.
