@dmitriarekhta - After a ton of back-and-forth discussing the IRQ affinity issues for the Intel i340, we found out that it is impossible to spread interrupts over multiple cores on...

Hmm... this looks _awfully_ similar to [52Pi's DeskPi Super6C](https://deskpi.com/collections/deskpi-super6c/products/deskpi-super6c-raspberry-pi-cm4-cluster-mini-itx-board-6-rpi-cm4-supported), which retails for $199. The Cluster Mini-ITX board is $200 on DWMZone and shipping was $40ish. Shipping is about the same...
