Will one of the mini pc's have space and be able to hold the Western Digital Purple drive?

Hi- I have been using BI 5.0 for quite some time, love it but am having issues with adding 2 new cameras. The first issue is with a Dahua bullet camera. I have it all set up over ethernet, works just fine. Problem is when I unplug the ethernet, it loses the signal- not picking up wifi. I'm sure this...
