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.

Excellent hack.

In case you're a masochist like me and want a lot more work on your hands, then you could remove the whole laptop mobo and make its own case and make it more compact in the process.

I've done this recently to make a standalone machine out of a busted laptop. This can give you a single, more compact unit with all the parts inside. You can improve the cooling and noise too (by using desktop fans). You'll maintain your laptop resale value too by not destroying the case and being able to put the mobo back in place in the future. Infact, with today's ram prices, the reason I went down this route is because you can get broken laptops with soldered in DDR5 ram.

    I've been pondering doing this to a broken iMac I've got.

    It got donated to me by someone who needed to thin out his studio a bit, so it didn't cost me a penny. But I took the screen off to give it a clean out and repaste, apparently didn't tape it in place securely enough as a temporary measure, so the screen fell off. And smashed.

    I did some swearing.

    However, it's still a surprisingly handy spec. 3.5ghz i5, 24gb RAM and a Radeon GPU. So I've been wondering about pulling the guts and turning it into a desktop, then making it my home server to replace the 2014 Mac mini I currently use.

    ponderings intensify

    I still have my black Core 2 duo Black Macbook, it's cut to a 4th of its size, a magnet is stuck near the lid sensor and it outputs video from the port on the side.

    I mean it used to output, I haven't tried turning it on in like a decade

    This can give you a single, more compact unit with all the parts inside.

    what if i want a multiplex, larger unit with several parts outside? can this help me accomplish that too?

    I've gone this route! Anything with a busted screen is fair game to me, though I haven't picked up any recently, mostly just tiny/mini/micros (and heavy on the lenovo tiny).

    But a custom hacked up laptop can be a great option especially with tight space to work with

    Edit: I'm surprised I missed your original post! I did the same, though what I reused was first a lenovo tiny, more recently updated with a digital signage player I picked up that I swapped parts out on - way more fun than a standard console imo!

    I thought about replacing the entire bottom part of the laptop, but then I looked at the screw layout and thought this is way too much effort for not much benefit. I am not lacking in rack space so I am okay with it being bulky.

    I've literally been considering exactly this for a media center. I already have a server built put of an old tower, but it's got limited specs and I don't want to bog down the other stuff running a gui and all that.

    This post is cursed.

    Not because of the insane jank, of course. That's on brand for self host and I love it.

    It is cursed because it has awakened something in me, and I can feel every old laptop in my vicinity trembling in fear.

    The fact that there exists an m.2 x6 port SATA adapter is the wildest part to me.

    This is the type of stuff I love to see the most when it comes to PCs. This to me is far more impressive then someone with a standard case, with standard RGB fans, standard AIO RGB cooler...

    This reminds me of stuff I did in college.

    Part of me wonders what chipset is running that adapter, and if you'd get a better one if you went for a miniSAS adapter rather than individual sata ports (enterprise port generally implying a better controller chip)

    Then realised there would probably be no use for such an adapter in enterprise so if you did get a different connector it would probably just be the same interface chip as whatever is in this.

    Is the laptop cooling ok with the lid closed? Or do you crack it open when actually in use?

    I like it. The OCD in me is screaming why you didn't use a dremel tool to cut the slot for the USB ports instead of using a rusty, dull, steak knife from the junk drawer, but that's just me. LOL

    So I actually have a setup similar to this, but with a mini pc (m.2 to 6x sata adapter, each one connected to a 4tb ssd - well eventually, only 2 are populated currently) and I did use a dremmel to cut through the metal top of the case and it was still a horrible sharp mess, even after I tried sanding it down. I ended up 3d printing a custom i/o shield to stop my cables (or fingers) getting sliced on it and that actually works really well!

    Edit: I dropped some pics of my setup in the comments on the original thread!

    This is really neat and I love it, but I am a bit worried about the power supply. Are you drawing power directly from the laptop? I'd just assume that spinning all four drives at once might cause spikes that I'm unsure if the built-in PSU is equipped for?

  • [–] 1 point 2 months ago (2 children)

    Yes and I have almost zero knowledge of hardware. So it might be something obvious but initial buying phase photo suggests you bought a card with 6 sata ports and connected them to the motherboard. Can you just connect sata boards to the mother board just like that without any extra work?

  • source

  • [–] [S] 4 points 2 months ago (1 child)

    I could, yes. The laptop has an M.2 slot that is intented to be used for M.2 SSDs, maybe you know them, they've gotten very popular. Almost any mordern motherboard has space for them.

    But instead of putting an M.2 SSD in that slot, I bought this adapter with SATA ports. And this adapter fits exactly in the same spot as the SSD could have. Then the SATA ports of the adapter can just be used as regular SATA ports as on any motherboard.

    bro doesn't get it. A substantial subset of selfhosting is using old tired stuff to make new sweet stuff. The only new parts on my machines are nvme ssds for the OSes and plugs and wire adapters. Everything else is yanked from an ancient unit or bought from ebay for pennies on the dollar of new. My services are free and my machines were close.
