There're a few areas you could scrimp to get to $1500. This is basically my build, but I went with 4 nodes, a bigger switch, and a cheap 4 pack of longer cables (10gtek's 4 packs have a decent discount). If the price of the Intel 660p has your attention for multiple capacity drives, I suggest an x470 or x570 mobo that can do x4x4x4x4 bifurcation on the x16 slot and then use a quad m.2 board without a PCIe switch for them (ones from ASUS and ASrock are ~$100 which can negate any cost savings). There are boards with a PCIe switch that will work with the above board, but they're very expensive.
If you get a MikroTik switch, use RouterOS because SwOS apparently has bugs beyond what I experienced. If you get one of their PoE switches, be careful with non-PoE devices. Mine was working fine, but I triggered a bug in SwOS and it toasted some gear; I need to have a conversation with MikroTik and the seller to see what can be done about what got toasted.
It says Passive DACs aren't supported, but I take that to mean that it's not tested and guaranteed to work, not that it won't work at all.
I'm using this passive DAC and it's working 100%.

For your server, you can get a Mellanox ConnectX-3 and run a longer Passive DAC to your CRS328. I do this and it works 100%.
