Building the Perfect Home Theater PC

We all know Intel NUCs are the ideal platform for a home theater PC (shut up, yes they are!). That’s a given.  I currently use a couple of older NUCs as HTPCs in my house, and as great as they are, it’s time for an upgrade. Not one to let an opportunity go to waste, I decided to go for broke and create exactly what I wanted, with all the bells and whistles.  I had a good idea of where I wanted to end up, but I wanted to flesh out the specs before jumping in.

The Plan

The first step in any journey is knowing  where you’re headed.  For my new HTPC, I had some specific requirements:

What I Want

Why I Want It

How I’ll Get It

Small Form Factor I like small PCs (I know, shocker, right?). They look great in a living room environment. Gotta be a NUC, obviously. But which one?
Quiet I don’t want something loud that’s going to distract from my viewing experience. Still a NUC. The most powerful ones tend to be the loudest, but they’re all quiet.
Horsepower (CPU and GPU) There are tons of super-cheap boxes that will play and stream. I’ve tried some, and the lag is irritating. They’re cheap for a reason. I don’t want something that “barely” works. Looking like an i5 NUC is the way to go. An i3 might be enough, but I want to be sure. An i7 will be overkill.
4k capability For that eventual day when I finally get a 4k TV. 4th, 5th, and 6th generation NUCs all support 4k, but the newer the better.
Built-in TV tuner I want to be able to pull in local stations and record for later playback. Experience tells me Hauppauge is the way to go, and I happen to have a GoRite NUC lid with one in it!
Built-in CEC capability I had my first experience with CEC recently and LOVED it.  Going single remote with my Smart TV and HTPC is awesome. I have a GoRite lid with the Pulse-Eight CEC module built-in. The module is for 6th gen NUCs, so I guess I’ll be going that way.

Set-top look and feel

It has to work without the need of a keyboard or mouse, and needs to be plug & play .

Kodi is my personal favorite for this. I’ll be using Libreelec for the first time.


Needs to be fast, and big enough to handle a dozen or so movie files. My movies are on my NAS, but I might want to copy some to the HTPC, in case I can’t connect to the network.

I’m going to opt for an SSD to make things super fast. I’m settling on 240GB. That’s plenty of room for storing the movies I want (maybe even some music).


802.11 AC WiFi AND gigabit ethernet. I want some flexibility on where I can use it. My router is in my living room, so I may not be able to plug in.

Given my other requirements, I’ll need to go with a 6th gen NUC, and they include AC WiFi and gigabit ethernet on-board, so I’m covered there.

The Specs

  • NUC6i5SYH: It’s got enough CPU and GPU to make viewing smooth, it’s tiny, it’s quiet, supports 4k and allows for a replaceable lid.  Plus it’s got on-board WiFi and ethernet.
  • 16GB RAM: I know this much RAM in an HTPC is probably overkill, but it was cheap and I may as well get it now.
  • 240GB PNY SSD: Nice & fast, and big enough to store some movies.
  • GoRite TV Tuner Lid: I still have the pre-prod lid with the built-in Hauppauge tuner…works great!
  • GoRite CEC Lid: I’ve opted to cannibalize the CEC lid by removing the CEC module and mounting it inside the NUC, then using the TV Tuner lid on the NUC.
  • Libreelec/Kodi: I’m going to go with my gut here and try Libreelec on this build. I’m assuming Openelec and Libreelec will be about the same, but I like to try new things.

The Build

Installing memory and an HDD or SSD in a NUC is about as simple as it gets.

“Making” the Lid

The next step was taking the two GoRite lids I had and combining them into one.  What I should have done is just get the Pulse-Eight CEC module by itself , but I already had the lid, so I decided to go a little crazy and pull the module out of it.  I’m weird like that…danger is my middle name.

The progress photos go through everything step-by-step, but in general here’s what I did:

  1. Remove the CEC lid from the NUC6i5SYH
  2. Disassemble the lid
  3. Remove the CEC module
  4. Remove the TV Tuner lid from the NUC5i3
  5. Install the CEC module next to the TV tuner
  6. Replace the 5th gen TV tuner cable with the 6th gen cable

Here we go!

Rather than take photos of the assembly, I recorded a video. It was much easier than stopping at every step to take a photo. Don’t worry, it’s short.



I’ve been a fan of Kodi for years. It’s got the perfect set-top look and feel for a home theater PC, and through add-ons it’s infinitely configurable.  Up to now I’ve preferred running it on Openelec. But someone recently told me about Libreelec, which is a “fork” of Openelec. I’m told it’s a bit faster and gets more frequent updates, so I’m giving that a try here.

Installation of Libreelec is more or less identical to Openelec: download the current version, unzip the image from the download, use an imaging tool to write the image to a flash drive, boot the system from it.  When you select “Quick Install” it will ask you which drive to write to, then confirm multiple times that you’re absolutely sure you want to wipe out whatever might exist on the drive.  That’s it. Simple.


I’ve learned a lot about CEC (Consumer Electronics Control) recently. For a solid description, check out Kodi’s wiki on it. One important thing is that each manufacturer can have a different name for it.  Another is that it doesn’t offer the same functionality on all TVs. For example, I have an older Vizio TV, and it has CEC on the menu. But it doesn’t offer the complete control my Vizio smart TV does. On the older TV, all I get is the basic playback buttons; play, FF, RW, skip, etc.  So your mileage may vary. CEC on my smart TV is…well, smart. It takes over the NUC entirely.

Also, with Kodi, there is no configuration required.  On first boot, a message pops up that Kodi is connecting to the CEC adapter…no drivers or add-ons to install. Just enable it on your TV and you’re off to the races.

One of the other awesome features of CEC is that since the remote is managed through HDMI I no longer need to worry about line of sight for an IR remote. That means I can put the NUC literally anywhere…behind the TV, in a cabinet, on the floor…wherever. As long as the TV has CEC, I’m good.

Setting up the TV Tuner

Unfortunately setting up Live TV in Kodi isn’t as “idiot-proof” as CEC.  There are multiple steps, and a few complicated configurations to get through.

You need two things to make a tuner work: A back-end service and a front-end PVR client. I’ve chosen TVHeadend for both.  It’s well integrated with Kodi, I’m familiar with it, and compared to some of the other options is fairly easy to set up.

The progress photos in the slide deck will walk you through how I got things working. They are not intended to be an all-inclusive step-by-step manual, just the steps I followed. for a more thorough how-to, I recommend this excellent write-up created by Team Kodi Member Zag. There is also good information in the guide on the site.

*The process of creating your network in TVHeadend is going to depend a lot on where you’re located. It involves selecting the type of signal you have in your area, the correct channels to scan for, and a few other items. For specifics on that part of the process, please refer back to the guide.  Once your network is created, you’ll initiate a scan, which  (if everything is working) will configure the muxes. What are muxes?  Beats me, but I can’t watch TV without them.

I also showed how I connected to my NAS for movies.  A similar process does the same for music files and pictures, but I plan to primarily use this for movies and TV. And yes that’s Eight is Enough…don’t judge me, it’s for my wife.

So, now that everything’s set up and running, here’s a quick video to show you the performance. In the video, the NUC is wireless, but only a few feet away from my router.

As you can see, it’s zippy fast. I can play from my NAS, stream, and watch TV with no lag or hesitation. I’m able to switch between add-ons quickly, and all menus are very responsive. I’m extremely pleased with the performance.

Update: some have commented on the overscan and the fact that the menu is in 720p. That’s due to my TV.  I have an older Proscan, and while it does go to 1080p, it defaults to 720p, and the default aspect ratio has the overscan. I just didn’t bother adjusting everything to make the video.  This will primarily be connected to my Vizio smart TV, which defaults to 1080p and no overscan, but it’s harder for me to record where that one is set up.

Final Thoughts

I did notice a slightly faster boot with Libreelec, but beyond that the performance between the two was not noticeably different. I do like Libreelec’s add-on update feature, and the fact that TVheadend is included as a standard add-0n (in Openelec you have to get it from their “unofficial” repository).  I don’t see a burning need to replace my existing Openelec setups with Libreelec, but I’ll most likely look to Libreelec the next time I need to build an HTPC. both run Kodi well, and with Kodi I get the set-top feel I was after.  When I turn this on, it doesn’t feel like a computer, it feels like something designed for home theater.

I can’t say enough good things about the tuner lid.  The Hauppauge tuner does an awesome job of pulling in my channels, and I don’t have an extra USB stick hanging off the back of my NUC.  The lid looks great, and means I have one less thing to carry when I take it with me.  Plus the addition of the CEC module means I don’t need to worry about an extra remote.

The NUC6i5SYH is rock solid and super-fast. Not much to say beyond that. It’s powerful enough that I don’t have to wait for anything. The fast WiFi means I can stream from the Internet or my NAS with no lag. It’s dead quiet in my living room.  I can’t hear the fan at all unless I get up and stand next to it.

Is an i5 with 16GB of RAM overkill for a home theater PC?  Probably. But I’m very happy with how this turned out. It has everything I want, and even a little bit more.  All-in-all, I’d call this one a solid success!

Now if only I could convince my wife we need a 4k TV…

      1. I like this build I have a 4k tv and have had it with my cable provider and would like to build this I am a little concerned about the 4k 30fps also wanted to know if you have updated your nuc build?


    1. Sadly I STILL haven’t made the jump to 4k. I’m thinking the prices are low enough that it’s time to get one though. As soon as I do, I’ll post a review and test it with some of the NUCs. The NUC6i5 should support 60hz, but I’ve never been able to test it myself.


    1. Well that sucks. Right now I watch Netflix through my Sony bluray players and Roku. Since I run Libreelec on the HTPC NUCs, Netflix isn’t a real option anyway. But still good to know. Thanks for the head’s up!


  1. Hey there, i was searching for the right way to reconnect my wifi cables to my nuc. The google picture Search brought me here.

    Thank you for your Screenshot (“SATA data and power cables disconnected.”). Even though i got the NUC6I5SYK it helped a lot 🙂


  2. Dipping my ancient toes into this world for the first time…and being old-school, I only recently upgraded from DVD’s and Blue-ray….anyhoo I digress. So google of course brought me here. I Have a Synology NAS onto which I ripped my DVD’s and so they sit in a folder on that thing. And I have an old NuC just like yours lying on a shelf gathering dust. And I have a 4K TV into which I usually plug a USB stick that contains he movie I want to watch. Which I normally copy off my Synology via a Windows PC. And the problem I face that brings me here is some of the larger formats (esp from Blue Ray Disks) will not play on my LG 4K TV. I guess it just doe snot have the cahoonas to do it. Does work fine with typical DVD rips though. Anyhoo back to your old page above, I have little doubt by now you have long moved on from this. But what I am trying to do is connect the NuC to the TV via it’s HDMI port (I don’t realy need 4K to be honest – my eyes are not that good anyway) and then wire it to my home network that includes the Synology. The Synology advertises “transcoding” and so I would want to be able to browse my library of movies/shows from the NuC that is pulling them from the Synology – either via ethernet or the “transcoding”. Is this scenario doable and am I looking to use the “Kodi” you mention to pull it all together and produce a decent experience?


    1. Hello! Yes I’ve moved on from what I did in that post. These days I have a NUC configured as a NAS with TrueNAS and connect to it using Plex. So I haven’t abandoned the idea of using a NUC for my media, I’ve just shifted from using it for the interface (Kodi) to using it for the NAS. I still highly recommend Kodi as it has addons that will allow you to connect to your NAS. But if you have a Roku or Roku TV you might look into Plex. It’s free, connects easily to many NAS platforms, and has an app or addon available for most solutions. I’m happy to offer more suggestions and help if I can. I’ve found the simplest solution to be the best one: NAS accessed directly on my devices via Plex. It’s pretty easy to set up and once it’s set up it just works. Plex has free on demand movies & tv too. Good luck!


      1. Thank you for responding to such an old thread! After I wrote the above I rolled up my sleeves and installed “Plex” on my 8-bay Synology NAS and told plex via its own interface which directories had movies and shows and it churned away and made images of all and seemed to sort them out. And then I went to my 4K LG TV and found that I could install Plex on that too. And it found my Synology and saw all the movies and shows. It kinda worked ok but was slow to navigate and respond so I connected the NuC (after installing Linux “Mint” to save me buying a windows licence) and there I also installed “Plex” and connected that, via the DisplayPort, with a convertor to HDMI I bought for $9 at the store. And then I hooked up a mini logitech keyboard with a built in track-pad. And wow that thing is fast compared to the TV’s plex. It actually works exceptionally well like this. Everything except the $9 dongle was lying on a shelf gathering dust.
        On my journey I did install “kodi” on the NuC but it did not discover my Synology, at least not in the way that plex did – instantly and without doing anything. It was not happy with the “SMB” protocol my Synology uses for some reason.
        The only downside I see with it all is that this “plex” player does not allow skipping back or ahead. Or at least I have not figured out how to do that. If you click on the timeline behind or ahead of where it is, it does nothing. But you can sort of skip using “chapters” at the bottom.
        Anyhow it is all a bit of fun and saves me copying to USB and then fumbling behind the LG TV every time I want to watch something.
        Thank you for being the inspiration to get this done!


      2. That’s awesome! I’m glad it’s working! I love my setup and we use it all the time. It sounds like you set it up similar to how I have mine. I have my TrueNAS running the Plex plugin. I haven’t seen any issues with sluggishness when using the Plex app on my Roku TV. Not sure why it’s slow on yours. When I watch movies I’m able to fast forward, rewind, and skip through no problem. Could be just the version you’re using.


  3. I will give Kodi another go after seeing the link you have provided! I did try both NFS and SMB but di dnot try to manually add it. I kind expected it to just pop up and say “Oh I see you have a NAS” kind of thing.
