That's why you set a budget...NAS's can very wildy in price depending on what you want. Need more than vague answers here TBH, it will benefit you the most the more specific you can get to your budget and needs.
It would be easy to setup a $300 cheap single-disk NAS without redundancy... or you could spend $3,000+ on a beast with high reliability, performance and functionality. So you really should know what you want to spend and what you want to do...different builds for different purposes.
Did you build it or have it built for you?
I really urge you to utilize Google and do some more research too beyond asking here, you will really benefit from that. Even simply Googling "Home NAS Solutions" would be a good place to start. Spend some time researching...take the suggestions here and research them too. It's your wallet, and you need to make sure you're investing with information rather than just other's opinions.
Build = Can build for less than buy, can customize to suit needs, more complex and complicated, noone to blame but yourself if something goes wrong, great experience, more risks. Easier to scale up depending on what kind of build you do. You can control what OS and services are provided.
Buy = Expensive, generally reliable, use proprietary hardware, OSes and services in many cases, warranty and customer support.
I highly recommend and love Plex. I use it on all my devices at home and on the road. Kodi works well too, but for me Plex was better. You will want a decent CPU (no less than a fast dual core, quad core recommended) for media stream management and handling multiple streams. You should research Kodi and Plex. They turn your home media collection into a Netflix-style UI sorta. Well Plex does. It works really really well.
This will save you on processing power and RAM, usually left to servers but many NASes are beefy enough to host virtual machines these days...which is why I ask.
60Mbps is your Internet speed, WAN (wide area network). I'm also talking about your LAN speed, Local Area Network. That will be critical to high-quality streams in your network. I recommend looking at PFSense for a really good router, but the Ubiquity EdgeRouter Lite3 and EdgeRouter X are both good, and add an Ubiqutiy UniFi AC access point for enterprise grade wireless.
Home grade router's I like are the TP-Link Archer series, Asus RT/AC66/68-series, you could even take an old PC, add a NIC card and install PFSense on it, or Untangled, or another open source routing software, or even go Linux and create the IPTables rules yourself. It depends on what you want to do. I'm assuming a home-grade router, but without knowing your experience and what you want, and especially what your budget and understanding of networking is...it's tough to really recommend anything specifically.
I do like Netgear, TP-Link and Asus products for home solutions, MicroTik has a decent home-grade router option, Ubiquity has some good home-grade options too as stated above.
