optx neon 9inch tube

[SameSuspect]

i wanna get one or 2 of these tubes to stick on my case, do i have to get one of these PC NEON Connector Kit so i can use it? these must power from usb i suppose?

if so how long is the usb cable? thanx

could these be used outside the case aswel? like behind the monitor which is roughly 3 n a half ft away

i thought maybe it would give a warm back light like them new flat screens you can get
