You don’t need three boxes under your TV. One home media server can hold every movie and show you already own and play them without touching your internet connection, handle couch gaming in 4K, and stream your own music library, if you build it with all three jobs in mind from the start.
That last part matters. Most guides pick one job for a build like this and stop there: it’s a gaming rig, or it’s a media server, or it’s a NAS replacement. This one is deliberately all three, because that’s the actual use case for a machine sitting in your living room.
One thing worth saying upfront: this whole project only pays off if you actually have a library to put on it. If everything you watch lives on a subscription service and you’ve never ripped a disc, downloaded a purchase, or kept a personal video collection, there’s nothing here for the media server half of this build to store. The gaming and music sides still hold up on their own, but the “never lose access to what you own” pitch specifically needs you to own something first.

What This Build Actually Has to Do
Before any parts talk, it’s worth being honest about the bar this machine needs to clear, because it’s higher than a normal desk PC:
- Enough storage to actually hold a personal library, not just a game install or two
- 4K output to a TV, with controller-first input instead of keyboard and mouse
- Quiet and cool enough to live in a living room 24/7, not a bedroom desk running for a few hours a day
That third one gets skipped in a lot of build guides, and it’s the one that determines whether this thing is pleasant to live with a year from now.
Old PC vs. New Build: What You’re Actually Trading
There are two ways into this project, and the honest answer is neither one is free of tradeoffs.
Repurposing an old PC is the more interesting build, and it’s the more hobbyist one. You’re not buying a fresh parts list, you’re figuring out what’s missing and filling the gap, which is a legitimately different (and cheaper) exercise than a new build. It’s also a real answer to e-waste: a tower that would otherwise sit in a closet or get recycled gets a second job instead. Non-critical hardware fits this role especially well, an old spare SATA hard drive that’s too small or too slow for a modern gaming rig is exactly the right speed and cost profile for holding a movie library that mostly gets read sequentially, not randomly hammered with I/O.
But here’s what you’re trading for that lower upfront cost:
| Factor | Old PC | New/Modern Build |
|---|---|---|
| Running cost | Older CPUs/PSUs often idle at 60-100W+, and this thing runs 24/7 | Modern low-power parts idle much lower, real savings over a year |
| 4K video decode | Older CPUs/GPUs may lack efficient hardware decode for HEVC/AV1, meaning some 4K files stutter or force power-hungry software decoding | Modern hardware has dedicated decode blocks for current codecs, smooth by default |
| Gaming ceiling | Whatever GPU is already in there is the hard limit, often 1080p or lower settings at best | Real headroom to actually hit the resolutions this build is meant for |
| Noise | Older tower fans and PSUs tend to run louder, more noticeable in a living room than at a desk | Modern cases and fans are meaningfully quieter at idle |
| Reliability | An old PSU or old drives running 24/7 in a new role carry more failure risk than new parts | New parts, new warranty, lower risk |
None of this means don’t repurpose the old PC. It means know what you’re actually signing up for. If the machine you have is genuinely ancient (pre-2015 or so), the running-cost math alone can eat the savings within a year or two. If it’s a few years old with a reasonable CPU, repurposing is the better call almost every time. If you want to go further with the repurposing angle, specifically making an old tower look intentional instead of scavenged, our sleeper PC build guide covers that ground directly.
Picking Your Case Size
This is where a lot of build guides steer you wrong by defaulting to small form factor because it looks good in photos. For this specific build, that’s usually the wrong call, and it’s worth explaining why before you buy anything.
A small form factor (mini-ITX) case typically gives you one GPU slot and two to four drive bays at most, often fewer once you account for GPU clearance and cooling. That’s fine if gaming is the main job and your library stays modest. It’s a real bottleneck for a build that needs to hold a growing movie and music library and fit a proper GPU for 4K gaming at the same time. On top of the slot limits, SFF shopping has its own tax: low-profile GPUs are a small, often pricier subset of what’s actually available, and SFX/SFX-L power supplies cost more per watt than standard ATX units while offering fewer options at any given wattage tier, something we’ve written about separately in the context of PSU upgrades generally. You’re paying more to get less room to grow.
A mid-tower ATX case sidesteps all of that. Full-size GPU clearance, standard ATX PSU selection, more drive bays, easier cooling, and it’s still compact enough to sit in a media console or TV stand, just not tiny. For this build specifically, mid-tower is the better default.
| Case size | Best for | One-line verdict |
|---|---|---|
| Mid-Tower ATX Case | This build, most people | Full GPU compatibility, real drive bay count, no SFF shopping tax |
| Small Form Factor Case | Gaming-first, modest library, compactness matters more than expandability | Fine if you know the tradeoff and are willing to shop/pay more for parts |
| Repurposed old tower | Already have one sitting around | Often already has the bays and full-size PSU this build wants, for free |
Quick Picks
If you just want a starting point before reading the breakdowns:
Best new build case for this project: Mid-Tower ATX Case — full-size GPU clearance, enough drive bays to actually grow the library, without the SFF shopping tax.
Best minimum upgrade for an old-PC repurpose: Internal SATA SSD for the OS drive, plus an External HDD Enclosure to turn a spare hard drive into usable storage without opening the case again.
Building the Media Server Side
This is the half of the build that replaces the “just buy a Synology” instinct, and it’s worth being upfront about when that instinct is actually right: if your library is small, a few hundred GB of ripped movies or downloaded shows, a single external drive is genuinely the better answer. Don’t build anything for that. This setup only earns its complexity once you’re actually pushing multiple terabytes and want the storage to grow with you, which is exactly what the drive bays in a mid-tower case are for.
| Storage option | Capacity fit | One-line verdict |
|---|---|---|
| External HDD | Small to medium libraries, simplest setup | The right answer if you’re not sure you need anything more complex yet |
| Internal Large-Capacity HDD | Growing libraries inside a build with drive bays | Cheapest cost-per-TB, ideal role for spare/old drives too |
| NAS-style Enclosure | Libraries you expect to keep expanding for years | Purpose-built for exactly this, worth it once you’re past “one drive is enough” |
Software-wise, Plex and Jellyfin both do the job of organizing and serving this library to your TV and other devices. That’s a setup conversation for another post, not something to walk through here, but the short version is either one turns raw files into an actual browsable library instead of a folder of video files.
Building the Gaming Side
The GPU question, and where integrated graphics actually stands
Here’s the honest version, not the marketing version: as of right now, even the strongest integrated graphics on the market (AMD’s Strix Halo-class chips, Intel’s Panther Lake-class chips) top out around 1440p to 1800p native in demanding titles, with upscaling stretching that further in well-optimized games. Older or budget integrated graphics (Ryzen 8000G-class and similar) are genuinely 1080p-class only. True native 4K gaming, at real settings, is still where a discrete GPU stops being optional.
That said, it can still run. An older or well-optimized title like The Witcher 3 plays comfortably at 1080p even on modest integrated graphics, and stronger integrated chips handle it at 1440p without much trouble. 4K is the actual dividing line, not “will it run at all.”
And here’s the part that makes integrated graphics a genuinely fine answer for a lot of people building this: your TV being 4K doesn’t force the PC to render at 4K. Output at 1080p or 1440p and let the TV’s own upscaler do the rest, that’s standard, expected behavior, not a workaround you need to feel bad about. If gaming is a nice-to-have on this build and media/music is the real reason you’re building it, integrated graphics at 1080p with TV upscaling is a complete answer, not a downgrade you need to fix later.
If real 4K gaming matters to you, though, that’s when a discrete card earns its place, and this is exactly where choosing a mid-tower case pays off, no low-profile restrictions, full-size cards, more cooler options. Our full gaming PC build guide goes deeper on picking a GPU tier if you want the broader context:
| GPU | Best for | One-line verdict |
|---|---|---|
| AMD RX 9060 XT 16GB / Intel Arc B570 | 1080p/1440p gaming with real headroom | The sane upgrade path once integrated graphics genuinely isn’t enough |
| NVIDIA RTX 5070 Ti / AMD RX 9070 XT | Actual native 4K gaming at reasonable settings | Where 4K starts being a given instead of a hope |
Controllers
For couch gaming specifically, a controller isn’t optional the way it might be at a desk. [AA LINK: Wireless Controller] pairs cleanly with Steam’s Big Picture mode or your platform of choice and is the difference between this feeling like a console and feeling like a PC you happen to be pointing at a TV. If you want the full breakdown of options, we covered this in more depth separately.
Cooling, for a living room, not a LAN party
Most gaming PC build content online is written for a desk, which means it’s optimized for cramming in maximum performance and treats noise as a secondary concern. That’s backwards for this build. Low-Noise Case Fans and a cooler chosen for acoustics, not just thermal headroom, matter more here than in a bedroom setup, because you’ll actually be sitting in the same room as this thing every evening. A mid-tower case gives you more room to do this properly too, better airflow paths, larger fans that spin slower for the same airflow, which is another quiet win over SFF, and it’s the same principle we walked through in our airflow-vs-fans piece.
Building the Music Server Side
The same storage that holds your movies and shows holds a ripped or owned music library without any additional hardware, this is genuinely just a folder alongside the video library, served by the same Plex or Jellyfin setup.
Where you take the audio output depends entirely on what’s already in your living room, and there’s more than one legitimate path here. If you’ve read our home office audio setup guide, the DAC-vs-receiver logic here is the same idea scaled up, a desk needs a different solution than a room you’re sitting across from on a couch:
| Setup | Best for | One-line verdict |
|---|---|---|
| HDMI into an AV Receiver | You already have a receiver and speakers | The real path, multichannel audio decoded and amplified by hardware built for exactly this, no separate DAC needed |
| USB DAC into a soundbar or 2-channel setup | No receiver, but you want better-than-TV audio without going full 5.1 | Legitimate middle ground, cheap and genuinely useful if a full surround setup isn’t where you’re at yet |
| Direct HDMI to the TV’s own speakers | No dedicated audio setup at all | The honest fallback, works today, upgrade later if you want |
Most people building this already have some kind of receiver in the living room, and HDMI into that is the cleanest path since it skips a separate DAC entirely. But if you don’t, a USB DAC feeding a soundbar or basic 2-channel setup is a real answer, not a cop-out, it’s just scoped to a smaller setup than full surround sound. And if none of that applies yet, the TV’s own speakers work today while you figure out what you actually want to invest in.
One more thing worth knowing if you’re smart-speaker-curious: this plugs in more easily with Google’s ecosystem than Amazon’s. Plex casts natively to Nest/Google Home speakers the same way it casts to a Chromecast. Alexa/Echo doesn’t get the same treatment, Amazon’s never opened up casting for third-party apps like Plex, so Echo support is limited to voice commands and playback control, not proper casting from your library.
Can It Talk to Your Consoles Too?
This is the question that comes up once people realize this box could theoretically do even more, and the honest answer is nuanced enough to spell out properly.
Can you use this as external storage for PS5 or Xbox games? Only in the way the console itself already allows, and it’s not about network storage. PS5 games only run from the internal drive or a Sony-licensed external SSD plugged directly into the console; a drive sitting in your media server over the network doesn’t count. PS4 titles are the exception and play fine off any external USB drive. Xbox Series X/S works similarly: Series X/S titles can be stored on a third-party external drive but need to be copied to internal or expansion storage to actually play, while Xbox One titles run directly off external USB. If you’re weighing whether you even need a console alongside this build, our PC vs. Xbox breakdown covers that decision separately.
Can you install and play console games straight from this box over your network? Not officially, on either platform. There are enthusiast workarounds using non-standard storage protocols that get talked about in forums, they’re not jailbreaking or piracy since they don’t touch DRM or game files at all, just unconventional wiring, but they’re fragile and outside what this post is walking through.
What does actually work, cleanly and officially, is the reverse direction, both consoles have native apps (Media Player/DLNA on Xbox, similar options on PlayStation) plus Plex apps that stream your movies, shows, and music straight from this box to the console over your home network. That’s not a workaround, that’s exactly the media server function this build already has.
Getting It to Your TV Without Internet
The actual point of this whole build is that it keeps working when your internet doesn’t. A direct HDMI connection is the simplest path and needs nothing else. If the PC lives somewhere other than right next to the TV, streaming over your local network to a TV app (via Plex or Jellyfin’s own apps) works the same way, since none of this depends on an internet connection once the files are local, only your home network. Worth actually testing with your internet disabled before you consider the build finished, that’s the one thing worth verifying rather than assuming. If building an offline-first game library alongside this interests you too, we’ve written specifically about that.
For the display side of this build, whether you’re deciding between a monitor and using the TV itself as your screen, our full guide to picking the right monitor or TV for every use case covers the 4K output and TV-as-monitor questions this build touches on in more depth.
This Rig Grows With You
A Synology box or a game console is a sealed decision. What you buy on day one is what you have. This isn’t that. Want better 4K gaming later? Swap the GPU, your mid-tower has room, and you don’t need to start over, skipping GPU generations and upgrading only when it counts is its own skill worth learning. Library outgrowing your first drive? Add a bay instead of buying a second sealed NAS. Want better audio? Add a receiver or DAC without touching anything else. Every piece of this build is a decision you get to keep making, not one you made once and are stuck with, and that’s the actual case for building this yourself instead of buying prebuilt, three separate pre-built boxes that each do one job, replaced by one you actually understand.
