that is the reason :

started sleeving the psu cables

first i made the p4 cable and the fan cable



closeup:



there is one problem with the p4 cable. it also has this new plug with 6 pins and this plug doesn´t fir behind the mb tray. so i had to remove it. looks not so pretty but you wont see it later.



built in:



you can see that i doubled the sleeve. i have to be some more accurate when i´m going to sleeve the Atx cable...
