Well my dad just bought some leds light to decorate his house as i found that fascinating i told him that i could put some in my Case xP ,so the next day i told him to get one for me too ...He got the Red leds

with animation stuffs (the things that we put on christmas trees xP )
But well that was pretty cool ,now that i want to do is to make it powerUp when i turn on the computer as the led animation is directly connected to the Wall Socket and it consumes 220 V @ 50 Hz i can't insert it in the 12 V from my
Psu,what i 've thought is firstly to solder it to the
PSU Wire coming from the wall Socket so no additional socket is in used because i lack those when my friends come to lan party every friday .I thought a lot of ways of installing the led but the problem is to make it running when my computer starts to RUN

Can someone tell how i could do that plz ... the led animation got 50 red leds so any idea ?
If more pic wanted just Ask
