16 BAY 4U DAS EXPANSION...question

https://www.serverbuilds.net/16-bay-das

I'm thinking about building something like this, but before I deep-dive into researching the build, I just want to make sure: "server" here is interchangeable with "desktop PC," right? Meaning, I can attach this thing to my desktop PC, as long as I have a free PCI slot for the SAS card, right?

Edit: oh, and I'm unfamiliar with racks; I can run that case without having a rack, right? It'll be ugly, but it'll work fine just sitting on a desk, right?

"These cables allow for the LSI 9201-16e to connect to your HDD/SSD in the DAS directly. You simply need to feed the cables through the Rosewill's I/O shield slot, where the motherboard would go. The cables should be plenty long enough if you have the two servers stacked right on top of each other."

Ah. That might be the sticking point...

Edit: they're 2 meters, I think I can make that work.

I think maybe I've figured out one reason to say "server" instead of "pc" or the like: it implies use of a NAS operating system, like FreeNAS, OpenMediaVault, or Amahi, which I won't be using.

I can use an SAS HBA controller with Windows 10, can't I?
