I used a tuniq tower 120 on my UD3R - it almost fits

, I just had to dremel off two bits off of the I-bracket (bits that stuck out for screw holes not used on the intel boards).
very very quiet - moderate oc (400fsb, e8600). the fan is on mobo control, almost never nudges off of low (only on heavy load) - the mobo kicks up the speed when the cpu starts to cross 50C. idle in the low 30s, iirc.
