I'm saying some of your sleeves don't have heatshrinks.
During my yester years, I did play with UV and it needs alot of patience and $$.
My advice, manage your cacing properly. Think of a theme. It doesn't mean all wires have to be sleeved. Sleeve those you think will bring out the best of the rig. Hint~ look for those wire which are long in between the molex or connectors. those extra insignificant wires can be kept hidden or unsleeved. Particularly the ones for the UV CCFL.
As for UV CCFLs you can get a pair or 2 pairs. top bottom back & front(near the HD).
Theme wise is important. once you have a theme you will grow or improvise from there. If you simply just chuck in a multicolored UV it might look haywire. I can't find my old pics but i have my friend's to share. this was like ages ago when we started playing on my old rig, now its more on standard CCFL on my stacker to lit up the floor in the dark room. Some hint on helping you up.

For yours i would say stick to normal UV components. get rid of the CCFL fans as well as the IDE cables. Hid it. play with green and yellow or double sleeve it (means both colours on the wires, refer to the image on top).
Molex connectors for extension are best kept hidden. if not possible, just do some wiring extension, make everything long and sleeve it. They look ugly. Get some UV molex to bring out the connectors connecting to hard disk or disk drives. it really shows that power is following through the connector and along the wires.
as for the CPU fan you did a good job. but I dislike the center fan being coloured green. why not remove it and add another yellow ring at the fins. place it near to the center of the propeller and remove the remaining green spots in the middle. Should remove the gloomy green effects and bring out some yellow contrast.
Above are some comments which I've provided and might conflict with some forumers. these are merely my point and view and i'm open to criticism. Well we're here to learn. Thanks
