  The Pi hat or OMV ?

 The pi, with directly connected spinning disks. Does the hat have its own extra power supply?

 I've managed to get a P4 I think to run one spinning rust disk without extra power.
Strictly it depends on the disk.
The pi hat for 5 drives has an external 60W PSU

  Used to run an external USB magnetic from
 a Pi4 ... worked just fine. TWO of them,
 well, not so sure.
  The 5-drive hat ... Philosopher says it needs
 at least a 12v/5a supply, esp if you're gonna

 This is promising!

  Gotta whip together SOME kind of holding frame.
 The Pi, hat and drives just kinda stick up there

 Go to your friendly neighbourhood 3d printer! =) Wouldn't that work?

 Umm ... that'd be a lot more expensive than just

Interesting! Had no idea 3d printing was that expensive in comparison.

 There exists some thin 'expanded aluminum' sheets
 that are normally used on the bottom half of
 screen doors - silver or pretty gold. They are
 easy to cut and bend tight. Look around in
 a Lowes store. I've used that for make-do
 enclosures before.

Strange, I get access denied.

 If you have one of these :

 I think of a Pi as "economy" and thus keep the

 Alas those cheap BeeLink/BMax units only have
 one SATA port so you can add an SSD drive in
 the bottom of the box. I think Orinco sells
 a "SATA hub" ... kinda like a USB hub ... that
