best 80mm radiator?

i'm thinking of building a cheap wc setup. the only problem is that i have a small case: lian li pc-6077. it only has fan mounts for 3 80mm fans, one on top, two in back. what 80mm rad would be best?

otherwise i could do something with the several open 5.25 drive bays but i have know idea what...

Thermochill and HWlabs Blackice Micro series would be your best bet.

You could drill out the top of your case in the emtpy drive bay area for a 120mm radiator maybe as well. Single or dual.
