I want to get a riserless board for my rig, but I cannot decide between these two boards.

Octominer vs Onda B250

The pros of Octominer:

1. Built-in CPU
2. Energy efficient CPU
3. Better Support Afterwards

The pros of Onda B250

1. Better chipset
2. Can replace CPU
3. Has additional 4+ PCIe ports which makes it 12 GPU mainboard

So where I live, I can get the Onda B250 + Celeron 7th Gen CPU at the same price as Octominer. And I can buy them quicker, because the seller is local.

What do you think should I go with the Onda B250 or Octominer? Any other pros/cons which I haven't mentioned? Can someone who has tried both tell me whether the Onda B250 has slightly more space between GPUs? It seemed that way to me from the pics and specs, but can someone confirm it?
