Linux PC build (2025)

Linux PC build (2025)


Hello,

it's me again.
Some of you might remember me from this post,
in which I was asking for feedback to build a Linux PC in 2025.

Stuff happened and I didn't went through with it.
So this still my first attempt at a build.
Well now I've got time and want to try it again.

As you may notice,
I've ditched the Z790-9 mother board in favor of a MSI PRO B650M-P.
My dream of building a coreboot-system is officially dead,
thus I decided to build an AMD-System.

Short Listing:


If you notice anything wrong
or have suggestions/improvements don't hesitate to point them out.

Thanks in advance!!!

Specifications:

Hardware is very similar to my own build from last fall, except I went with a 7800XT. it's been running CachyOS since then and works superbly.

Since you have a similar setup. I have a question for you.
The motherboard was released in 2023. I've read that most suppliers drop the firmware support after 3-5 years.

What I am asking is, is it worth in your opinion to buy this motherboard or should I look for a newer model instead?

I don't know, I never really thought about that. I had my previous mobo for about 10 years and at that point it was becoming a problem, but for the first 7 years or so it worked fine. After 7 years there would be a new CPU socket anyway, so it would be a good time to upgrade.

This is my build:

  • AMD Ryzen 7 7700X 4.5 GHz 8-Core Processor
  • Thermalright Frost Commander 140 BLACK 95.5 CFM CPU Cooler
  • Asus TUF GAMING B650M-PLUS WIFI Micro ATX AM5 Motherboard
  • TEAMGROUP T-Force Vulcan 32 GB (2 x 16 GB) DDR5-6000 CL30 Memory
  • Silicon Power A60 2 TB M.2-2280 PCIe 3.0 X4 NVME Solid State Drive
  • XFX Speedster QICK 319 Core Radeon RX 7800 XT 16 GB Video Card
  • Lian Li O11 Air Mini ATX Mid Tower Case
  • Corsair RM850x (2021) 850 W 80+ Gold Certified Fully Modular ATX Power Supply

I am curious why coreboot is important?
Because coreboot is the only way for us to be in full control of the hardware. Any other way there is microcode which is closed source and we have no idea what it is doing. It has full control to everything.
@Jeena I grant you that is true, but under Linux, the kernel talks to the hardware directly after boot, not through BIOS calls. About the only time you would talk to the BIOS after boot is for sleep/suspend, or in rare cases such as the server my friendica instance runs on, for temp/CPU speed control because Linux kernel has issues properly using the MSR on the i9-10980xe, oddly it does not seem to have the same issue on the i9-10900x which is a ten core CPU in the same family, so I am forced to depend upon ACPI since talking to the hardware directly in this specific case is problematic. If you were running Windows or if you had weird hardware that is somewhat broken under Linux like mine, I can see the need, or if a laptop and you wanted sleep/suspend functionality. But for what you describe it isn't clear the benefits. And there are some risks like it probably isn't going to do the extensive memory training of a more advanced UEFI bios like American Megatrends, so your memory access may not be as efficient as it could be, and you're more limited in hardware selection.
Because it lets us disable Intel ME
@marauding_gibberish142 I personally find the Intel ME a useful feature, it's nice for example to be able to upgrade BIOS without a CPU and/or memory, this has allowed me for example to upgrade the BIOS to a version needed for a newer CPU on a board with a BIOS that didn't initially support it without needing the older CPU to perform the upgrade. And from a security standpoint, if you do not enable and configure the network stack, and you don't have a DHCP server available to it for it do so on it's own, I really don't see what it can do that is harmful.

How do you not configure the network stack? If you have an Intel NIC on the motherboard/any PCIE lanes in theory it should be able to connect.

What worries me is that someone could perform a reverse shell on my system with/in addition to a magic packet and get full ring 0 access to my system. I'm investigating network monitoring tools that can help me find traces of ME on my network.

How did you list your hardware like that? Where it shows the key specifications for each part as bullet points, not the bullet points though, if that makes sense. I know how to make bullets, I mean the data.

Was is generated with a script or did you copy and paste individual part stats from their website specs or some other way?

I have a few ways to generate info, like with inxi or searching pcpartpicker, but there often there is not enough info, important info that is missing, far too much info about stuff I don't care about or I have to spend a lot of time searching for specific data and have to copy and paste each feature for each part individually which can be too time consuming.

What you have shows pretty much exactly what I would like, so I could easily share when needed.

Why the 7900XT and not a 9070 or 9070XT? Stock issue?
Both are overkill for 1080p gaming but if you're trying to future proof, wouldn't the newer card with FSR4 be the better option?

I couldn't find a 9070XT at around MSRP anywhere, I wanted to use them in a combination with other GPUs for AI. Know where I can find some?

AI is a different beast altogether, maybe I missed that use case in this or your previous post. From what I've read, rocm support for the 9070 cards is still being worked on.

Edit: Just learned to stay away from the keyboard until after coffee. Also, GPU pricing is horrible all around.

What do you plan to do on that graphics card? Is that 20GB VRAM? That sounds nice, but not being a NVIDIA it lacks at least the CUDA cores which are necessary for many AI use cases which I have.

I think Ollama supported ROCM especially with the older AMD cards?

I have ollama running locally on my RX9070, I have to use kernel 6.14 since it's such a new GPU.

The 16G VRAM means I can run decent models, faster than I can read.... currently running gemma3:12b, it's crazy fast.

How quantized? I don't think 16GB of RAM is enough to run a full fat 12B model at FP16 but maybe I'm wrong.

Nvidia cards are just too expensive
