Yep, that's the one I have (you see it briefly in that video I linked). I had the OS drive up there too, but I think I put the optical drive back in when I put it in storage .. also added a half-height video card with DisplayPort/HDMI since I didn't have any VGA monitors 😅

I have 14TB ~ 23TB drives now. Native encryption full backups took 2~4 days 🤣 ... there are unofficial firmware hacks to get SATA3 working on them as well (the SATA2 is another bottleneck)
