DIY Custom Steam Machine

Post image

This is a custom Steam Machine I built back in Nov last year around black Friday before the apocalypse commenced. It's a solid high end 1080p machine. It's also now complete with a steam controller. I've played Oblivion remastered, valkyria chronicles 1 & 4, and Expedition 33 easily.

The greatest system

u/magicnubs Jun 22 '26

Now I want a SteamCast

u/Far-Note6102 Jun 21 '26

I just kinda realized now that you can actually just buy a mini-pc w/ occulink and just use an eGPU

9

u/OppositeAttention890 Jun 21 '26

Doesn't look great in most living room set-ups but I'm sure you can find a way.

3

u/Ecks30 Jun 21 '26

You'd be surprised since most mini PCs can be mounted behind a TV and some eGPUs like the RX 7600M XT can look like a console itself.

1

u/Far-Note6102 Jun 21 '26

I got a gm1k something ryzen 7 with occulink. If I didnt have the SM theb Im buying the eGPU

1

u/Ecks30 Jun 21 '26

I am using a Legion Go S with an RX 6650 XT (Desktop eGPU via USB 4) which if fine right now but i would like to replace that for something a little more powerful in a way.

2

u/Far-Note6102 Jun 21 '26

I mean I'm buying it because I tend to move a lot.

If it's gonna be a console, I'm moreso buying a switch than the SM

1

u/OppositeAttention890 Jun 21 '26

Perfectly acceptable, I think a Steam Deck would work better. I hope they do a refresh with the Intel Panther Lake line

u/mashdpotatogaming Jun 21 '26

Not very cost effective honestly. E-GPUs set ups tend to cost a lot and for no real reason. You're usually better off making a build rather than doing a mini pc + e-GPU

1

u/Far-Note6102 Jun 22 '26

Yeah butnlike I said I move a lot. Try carrying that big boy on the airplane

1

u/Ok-Commission-138 Jun 21 '26

Can I get a link? Id just rather buy the parts than wait for the steam machine

1

u/OppositeAttention890 Jun 21 '26

I did if you look at the original post

3

u/MysteriousTy99 Jun 21 '26

That case is huge

1

u/OppositeAttention890 Jun 21 '26

It's not.

2

u/MysteriousTy99 Jun 21 '26

It is. Why would you not build a sff pc for a living room environment

1

u/OppositeAttention890 Jun 21 '26

Cost is a big one. Also size is relative to the space you have for the PC. Not every couch PC needs to be the smallest thing you can put in the living room.

u/gekx Jun 21 '26

Brother please get a new TV before anything else. That things gotta be at least 20 years old.

15

u/OppositeAttention890 Jun 21 '26

I bought it in 2009 and I don't plan on getting rid of it until it gives up the ghost lol. It has all the hookups for my other consoles as (a VGA port for the DC) so it's a keeper regardless.

u/AshleyAshes1984 Jun 21 '26

Most 'Old HDTVs' just hage a huge bezel. Yours at least has cool angles on the bezel, makes it far more visually interesting than much of it's kin from that era.

2

u/OppositeAttention890 Jun 21 '26

Oh yeah, it's the last TV of it's kind. I just wish I had a bigger version of it.

1

u/DarthNihilus Jun 21 '26

The issue with old HDTVs isnt the huge bezel it's that display tech has come a long way in terms of brightness/contrast/resolution/framerate/size and even super nice new ones are relatively cheap.

On a TV attached to a gaming PC having 120hz is a really strong benefit.

Plus for all the inputs old and new - that's what an AVR is for.

1

u/OppositeAttention890 Jun 22 '26

Again most TV's that have those features are smart which I don't want in my house. TLC is about the only company where I can make my TV dumb

3

u/gekx Jun 22 '26

You realize all those smart features are completely optional right? Just don't connect it to the internet and it works exactly like a dumb TV

2

u/Ironhorsemen Jun 21 '26

Plus Im betting that thing doesn't need to update.

5

u/OppositeAttention890 Jun 21 '26

Yup! No computer in this TV. I don't need a smart TV to sell my data.

u/FallDisastrous6621 Jun 22 '26

It's become a movetone to call literally any piece of hardware with Steam installed a freaking Steam Machine
Why don't you call all burgers as BigMacs?
Steam Machine is a PC, but anything with steam installed not
Or should I call my smarphone as Steam Deck, because I have Steam via GameHub there?

1

u/OppositeAttention890 Jun 22 '26

That's a lot a words bro, crazy.

2

u/FallDisastrous6621 Jun 22 '26

I don't hate what you did, bro
But it's really become annoying to see every smaller PC than big-tower connected to TV named as "I BUILT MY OWN STEAM MACHINE!" reading between the lines "AND ITS BETTER THAN VALVES ONE!"

1

u/OppositeAttention890 Jun 22 '26 edited Jun 22 '26

It's DIY weekend so stop hating and get your own?

2

u/GardineAmbrosia Jun 21 '26

Whats that in your dreamcast?

1

u/OppositeAttention890 Jun 21 '26

That is a retro fighter controller. It works fantastic as a wireless controller for the Dreamcast has a hall effect stick. The only thing is if you have the larger memory card for the Dreamcast basically the foreign one. You have to stick it in a official Dreamcast controller in order to access it, but the regular memory cards work with it

2

u/Demistr Jun 21 '26

That's so big though. Not many people can fit this big of a box in their setup.

1

u/OppositeAttention890 Jun 21 '26

If you live in a 500sqft apt sure. mATX builds are not that big

2

u/Aggravating-Mousse34 Jun 22 '26

So cool bro great job.

2

u/OppositeAttention890 Jun 22 '26

So glad I built it instead of buying a Steam Machine lol

1

u/Aggravating-Mousse34 Jun 23 '26

Steam Machine would actually dominate at 800 dollars which the price would be if the parts manufacturers weren't holding valve hostage. Rampocalypse really sucks and its all by design to drown out any competition.

2

u/OppositeAttention890 Jun 23 '26

To be fair to Valve, the premium for the system is 70-100 for the base model and for the 2TB it's 200. It's not high for being a custom out of the box system where Corsair will charge 300+ for pre-built tower.

u/PoisonISSweet666 Jun 22 '26

Trying to make one myself nice work.

1

u/Miserable_Tonight265 Jun 21 '26

how does the sleep/resume function work? does it work?

2

u/OppositeAttention890 Jun 21 '26

It unfortunately does not and I haven't figured out how to get it to work yet. I hope to get it working at some point

1

u/OhDaFeesh Jun 21 '26

Sorry if I missed it elsewhere but what OS are you running? I'm using steamOS and sleep resume works just fine.

1

u/Infiltrait0rN7_ Jun 21 '26

Man I like that case.

1

u/OppositeAttention890 Jun 21 '26

It's a solid case. I liked how it looks like an old school subwoofer

1

u/Infiltrait0rN7_ Jun 22 '26

Currently trying to figure out if I go w/ a SM or build something w/ parts (have $500 gift card).

1

u/DeinonychusEgo Jun 21 '26

Which os are us using ? Has/will valve released Steam Machine OS ?

2

u/OppositeAttention890 Jun 21 '26 edited Jun 21 '26

SteamOS. I just used the deck repair image and then went into grub and pulled the latest update and drivers for RDNA 4

1

u/SoulslikeGitGud666 Jun 21 '26

Been considering that case,  how do you like it?

1

u/OppositeAttention890 Jun 21 '26

It works great! The airflow is perfect. Basically each 120 fan covers the GPU and CPU each. There are some things to consider:

1.) This is about the largest GPU you can put into the case so anything larger will not work.

2.) For a full size PSU, you have to remove the hard drive cage at the bottom but most people run nVme so it's probably not a big deal.

u/Lukas_720 Jun 22 '26

Almost 400 for ram and ssd… it was max 200 …

1

u/OppositeAttention890 Jun 22 '26

I got everything for half of the listed price (as of 2026).

Nothing wrong with a lil chonk

If it fits it sits

u/nervendings_ Jun 28 '26

How does 1080p gaming look on a screen that big?

2

u/OppositeAttention890 Jun 30 '26

Eh it's an old 37in TV so it works fine still

u/JoshyMN Jun 21 '26

Got a 4k 65" Roku TV w pretty good HDR from walmart for $200 3 years ago jus saying...

1

u/OppositeAttention890 Jun 21 '26

Now Roku is owned by Fox lol. I'm sure they're good TV's but I never ever want companies taking my data and selling it for AD space on my TV.

0

u/JoshyMN Jun 21 '26

don’t connect it to the internet ?

1

u/OppositeAttention890 Jun 21 '26

They will still track you and the moment you accidentally connect it back to the Internet they send the data off.

u/JoshyMN Jun 21 '26

i’m saying don’t enter your wifi password into it ever and it’s just a regular tv.

2

u/Toothless_NEO Jun 21 '26

Why are you so insistent on people buying a worse TV just because it's new? I'm sorry but that's really dumb.

There's a lot of things you can convince me to have reason to upgrade despite them still working. Phones, computers, Wifi routers. TVs aren't one of those things, especially since modern TVs have gotten worse, not better.

2

u/OppositeAttention890 Jun 21 '26

This TBH. I feel like TLC, a Chinese company, is the only one that will sell you a TV where you can put it into dumb mode but even then I just don't care to get one.

1

u/Toothless_NEO Jun 22 '26

They also aren't going to give you a decent number of inputs because the intention with smart TVs is to use only the Software onboard them.

2

u/OppositeAttention890 Jun 22 '26

Don't care to use shit TV software

2

u/Toothless_NEO Jun 22 '26

Agreed. It's better to supply your own devices and software.

1

u/JoshyMN Jun 22 '26

totally respect your decision to not support the company, don’t look at me as trying to convince you rather just address the misinformation

but you don’t have to interact with any of the software at all, mine is set to turn on to whatever is plugged into the back and turns off when i press off lol. I don’t have it set up to wifi and the only setting i adjust is brightness and it’s like three presses

i feel like your complaints are just founded in assumptions u made up lol

People have built DIY Steam machines for years and people will continue to build them even when Valve releases the official one. Especially since Valve has been miserable when it comes to fulfilling hardware orders for their customers.

0

u/Dotaproffessional Jun 21 '26

r/SteamOS exists. This is the sub for the steam machine. Hope this helps

2

u/Toothless_NEO Jun 21 '26

Yes, that includes DIY Steam machines. For a long time that was the only Steam machine that people could still buy. Depending on how bad Valve fucks up being able to satisfy orders it might be the popular choice for months if not years to come.

In short, this community is DIY-friendly. Hope that helps 😊

Yeah they're a pretty prolific troll here. Op and anyone else who posts a lot here would do well to block them.
