The cases from China will me cost way too much because of shipping to Canada ($180+ per case).

So, I got one of these cases for less than $ 200 CDN. It's depth is just a bit too short for the Onda 8 GPU Mobo. ( I still have my dead Onda MoBo.) Anyway, I will use it with my 7 GPU MSI 170A Pro Carbon MoBo rig.  There's lots of room to add fans to cool everything.

I  ordered the Thermaltake Core X9 ( $230 CDN) and will try it out for size with the Onda 8 GPU MoBo. If it fits, I will buy another Onda 8 slot board. If not, I can still use it for my 12 GPU Biostar MoBo and likely put 10+ GPUs in this case.
