As I said it's dependant upon your house wiring. I have powerline adapters running to my cinema room and steaming full 4K remuxes with no issues.
They won't however stream to the lounge, probably because of the wiring circuit, so I've had to run ethernet in there.
I don't think I'd leave my NAS in a closed cabinet unless it was very large or had good airflow as they can get quite hot.
My Synology NAS sits in a cupboard just fine.I just make sure it's got room all sides to keep ventilated but it never spins the fan up, even when applying updates or other CPU intensive tasks.I also remove it and air dust it once a year.
I can't hear my NAS itself, but the WD Reds are noisy track hoppers.This doesn't bother me in my home office, but it would if it was in my lounge, but then there's no enclosed space there to site it.
Lastly for a large 4K movie collection, I'd be looking at the bigger NASes, say 5 bay and up.There's one on the bay of e if you fancy trying your luck.
Thanks everyone for the help. I've just bought one from the classifieds which should hopefully do for just serving up media etc.

I'll have to wait until I get it set up before deciding whether or not it's too noisy in my room. Chances are it will be by the sounds of things, so I'll likely have to put it in the next room, which will take a bit of work but is doable.
SSD drives can help eliminate noise though they come at a cost, the price of 1TB SSD drives has dropped quite a bit, down to £116 for crucial 1TB models.
Synology NAS can go quiet under the right conditions, under control panel->hardware & power
* there is a fan speed mode, besides quiet mode there is a low power mode which stops the fan so long as the temp remains in cool range, if the room does not get too hot you can use low power mode with no fan noise from NAS.
* in same area there is power schedule tab, this allows you to power on/off the NAS, very useful if the NAS is only ever going to be used at certain times.
* you also have HDD hibernation, this will spin down the HDD's making it much more quiet so long as there is no activity, you can set the time period to wait, however be aware some third party apps you may install on the NAS via Syno app store will block this function as they may be always scanning at intervals.

I'll definitely try some of that, thanks!
I'd considered going the SSD route but I think I'd rather put a bit of effort into drilling into the next room than pay that much, and spend the saving on larger storage. I'm thinking two WD Red 4TB to start with.
Not sure about Synology, but unRAID has the ability to utilize SSDs as cache drives to speed things up data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7
Yes.Some Synology NASes even have M.2 slots for caching so to not absorb the front bays.1 for read caching, 2 for write (AFAIK).There is absolutely no point for 4K content though or backups though.
8TB is the sweet spot for price/storage at the moment.
Considering you're bought a 4-bay to give you more space I wouldn't bother with 4TB drives. Also depending upon how you configure it, if you use a traditional RAID then you're restricted to the size you first put in it, so all the drives would have to be 4TB.
Isn't the DS413 restricted to 4TB drives? If not, I'll happily go with 8TB!
