Build or Buy NAS ?
I'm currently into buying either the 218+ or 918+ synology, unsure if ill regret not having 4 bays for expanding options?
Hows all yours set up?
#want want it to stream and work with photos and movies like a mediacenter aswell

Raspberry Pi + a few USB sticks are my NAS :P

I use a Proliant Microserver with FreeNAS

@filthyranter This is something I researched. Aren't the usb ports slow as fuck?

Synology NAS's are quite nice.

I have qnap ts-431p and I am quite happy about it. I can login using ssh and have root on it.
It also have 4 bays, can stream to chromecast.
Have mobile apps for it like backup my phone photos automatically or browse nas and get data from it to my phone.
Supports time machine.
There is also docker like containers on it but didn’t have time to check it out.

My main requirements for device were mobile apps, root access via ssh, and time machine so it suits my needs.
I didn’t wanted to waste time to manage another server so I was looking for dedicated device.

First decide what are your requirements to buy such device.

@Jifuna Not that slow.

I went with a synology DS918+ and 4X6TB WD Red.
Fullfills my space, remote and casting needs. Did lookup qnap, but thats mostly 1080p streaming, where synology did 4k and just some more features i gotta have :p thanks for all your input, was good for thought
