Me But probably not by much

Hmm if I have all the CPU blocks running in parallel (or mostly parallel), think I'd be able to get by with a dB-1 for each CPU block? So there would be one tube coming from the radiator, splits into 2-4 separate tubes, each of which has their own dB-1 and CPU block, and then they all join back up again to go to the radiator. Or something like a D5 per 2 blocks (since I can fit two PCs per shelf)?
