...but please tell me you will at least have room in the case for standard ATX power supplies. The tangle of wires on the outside of the machine is really quite ridiculous. It was understandable on the Jupiters due to the time constraints but there is really no excuse for it on the Neptunes.
Perhaps, but the reduced footprint brought shipping costs down significantly. I'll pass the concern on though.
This is a MUST if we want to use datacenters. Also, server power supplies would fit much easier and are capable of higher wattages. Also, server power supplies aren't necessarily more expensive than ATX PSUs when calculating watts/$.
