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.

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!
