shudnt be any prob wif HAF932 la .
u can install dust filter if u want .
d front panel oso is removable .
for sound dampening im not sure . but d speaker sound will overcome d graphic card sound .
its not like ur gonna run d fan at 100% speed and/or using DELTA 220CFM fans rite ?

if ur using both of these , any casing also would create hellish machinery sound .
