What I have

I have an old Acer Aspire A515-51G and I also have a desire to have a home server. In combination this creates a need for the laptop to carry more HDDs than it can from factory. Usually it can take one M.2 SSD and one 2.5" SATA drive.

What I want

I want to make the laptop able to run at least 4 HDDs in RAID 5 for storage and have one SSD as boot drive.

What I did

The buying phase

  • 4 HDDs
  • M.2 to SATA adapter
  • 12V/5V SATA power converter
  • 12V 10A power supply

The designing phase

I needed space to hold the HDDs, so I designed a 3D printed a cage to attach to the bottom of my laptop. Two 80mm fans can be attach to it. You can see it on printables. Also I remixed a tray (here is the original) so the HDDs can slide in and out of the cage.

.

The assembly phase

A cutout at the bottom of the laptop was needed to give access to the SATA ports of the adapter.

I put a 2.5" SSD into the already present place for it in the laptop.

Then the cage was attached to the laptop, the HDDs were put in their trays, the trays inside the cage and the cables attached to the adapter and HDDs.

    It probably uses less power than a NAS, while having more CPU power and RAM

    Plus nothing beats and upgrade using what you already have.

      No, but installing the adapter itself is exactly the same as installing an M.2 SSD. Afterwards you treat it the same as regular SATA ports in a PC. You connect the SATA data cables to the HDDs and the adapter, and provide power to the HDDs. Power is not handled by the adapter, this is what the DC 12V/5V converter is for.

      Does this help you?

    Ok, why get a case if you can just screw em on?

    Also, add a fan to the HDD tray (can double for the laptop).

    I did something similar awhile back. Since you already cut open the bottom of your laptop I would suggest you cutting another window over the CPU and adding a large plate of aluminum as a shelf between the laptop and you hard drives. Then add a shim so the CPU cooler and plate touch, then you will have a passively cool laptop server with an internal UPS battery.

      I am not worried about cooling. The system will be in a cool place, the HDDs are cooled by the 80mm fans and the laptop has its own cooling system that I just de-dusted.

        Any issues with the M.2 to SATA adapter? I’ve heard rumors to stay away from them, as the SATA controllers tend to overheat. Just wondering how the M.2 card behaves under load while trapped beneath the laptop.

          Fair, however, I have run this laptop in a different 24/7 setup for years and it was fine. Also the laptop lives in a place where noone needs to hear it.

    Very cool looking project. I’ve been stripping motherboards from my busted old laptops recently, and am setting one up as a HiFi-ish HDD player at the moment. Next step would be some sort of NAS/homelab.

    Since you’re already 3D printing parts, is there any reason you didn’t just pull the mobo, connect the drives and made a neat headless case for it all? Not that I don’t appreciate that weird lapdozer you made! 😂

      This way I have keyboard and screen attached in case I want to use it, and designing around the motherboard seemed more work for not much benefit. I do have enough rack space to not need to care about bulk, the server will not be in a place anyone can hear it and noone will regularly look at it as well, so it does not need to be pretty.

      I opted for easy maintainance and tried to not overengineer it, so that it can get used sooner.

        Fair, I thought that might be your reasoning 🙂 Either way, I’ve added a few of your purchases to my own wish list for future projects. Thanks for the inspo!

        Thats a relief, I was worried you were completely deranged. :D

        What NAS software? Does the nvme to sata thing properly pass through the disk serial numbers? Truenas gets very pissy if the disk serial numbers aren’t passed in properly.

    Somewhat off-topic: How could I crosspost to more communities, like DIY on beehaw or 3D printing communities? Would I need to create a completely new post on them? Or just post the link to this post?

      At the top of the Lemmy UI underneath your title is a row of option icons; the icon to the left of the last icon with the three vertical dots - looks like maybe the Copy icon, sorta - is the Crosspost option. Click it and follow your nose, the new community dropdown is at the bottom of that next screen.

    My only worry really is the m.2 to multi sata adapters reliability.

    But it doesnt seem like there are sata-usb adapters with data only, that allow a single power source like yours 🤔

    I might do something very similar with a mini PC

      These m2 adapters are known to overheat, but otherwise they are much more reliable than usb to sata adapters.

      I’ve had a 5x version (op has the 6x) in my fileserver for easily 12+ months. Never given me an issue, just chugs along attached to an itx motherboard. I’ll probably need to get another one at some stage to keep up with the collection of content.

      Using a pcie to 4x nvme riser, luckily this motherboard supports bifurcation so its single 16x pcie could become 24 sata drives if I ever required.

      USB is far more unreliable compared to these M.2 to data adaptors from my experience.

    That’s one nudge away from a disaster. I’d 3d print a shroud for the sata ports/connectors that uses the laptop base screws to hold it in place. That way the laptop could slide off the drive cage without every sata port snapping off.

    I would probably add rubber/etc feet on the cage to keep it from vibrating around as they spin, and maybe a handle for carrying! It’s a mobile laptop after all… :) What if someone tries to snatch-and-grab a HDD while you’re getting a coffee, do we have an alarm system? Lo-jack?

      This reminds me of the homeless guy I saw walk away from his shopping cart, spin 180 while clicking his imaginary FOB, then mouthing “Boop Boop”.

      Needless to say I lost it, core memory.
