yes
I used mega.nz to create a number of free storage accounts of 20GB each, used RAIDRIVE to map these to network shares for my plex server
RAIDRIVE free version allows only 8 maps, so I got 8 x 20GB = 160GB for free
mega.nz + free RAIDRIVE is a bit clunky as it only allows read access...you need to use mega.nz web page to upload/administer...not a big deal once you have setup and if you hardly ever change
I did come up against some network limits with mega.nz...not sure if it was related to some admin I was carrying out, or whether it would impact me in normal usage
when I hit this limitation I decided $100 for 2TB for hosting on own h/w wasn't such a bad deal
