Looking to build my first PC in almost 30 years; What should I be on the look out for?

It looks like !buildapc community isn't super active so I apologize for posting here. Mods, let me know if I should post there instead.

I built my first PC when I was I think 10-11 years old. Built my next PC after that and then sort of moved toward pre-made HP/Dell/etc. My last PC's mobo just gave out and I'm looking to replace the whole thing. I've read over the last few years that prefabs from HP/Dell/etc. have gone to shit and don't really work like they used to. Since I'm looking to expand comfortably, I've been thinking of giving building my own again.

I remember when I was a young lad, that there were two big pain points when putting the rig together: motherboard alignment with the case (I shorted two mobos by having it touch the bare metal of the grounded case; not sure how that happened but it did) and CPU pin alignment so you don't bend any pins when inserting into the socket.

Since it's been several decades since my last build, what are some things I should be aware of? Things I should avoid?

For example, I only recently learned what M.2 SSD are. My desktop has (had) SATA 3.5" drives, only one of which is an SSD.

I'll admit I am a bit overwhelmed by some of my choices. I've spent some time on pcpartpicker and feel very overwhelmed by some of the options. Most of my time is spent in code development (primarily containers and node). I am planning on installing Linux (Ubuntu, most likely) and I am hoping to tinker with some AI models, something I haven't been able to do with my now broken desktop due to it's age. For ML/AI, I know I'll need some sort of GPU, knowing only that NVIDIA cards require closed-source drivers. While I fully support FOSS, I'm not a OSS purist and fully accept that using a closed source drivers for linux may not be avoidable. Happy to take recommendations on GPUs!

Since I also host a myriad of self hosted apps on my desktop, I know I'll need to beef up my RAM (I usually go the max or at least plan for the max).

My main requirements:

  • Intel i7 processor (I've tried i5s and they can't keep up with what I code; I know i9s are the latest hotness but don't think the price is worth it; I've also tried AMD processors before and had terrible luck. I'm willing to try them again but I'd need a GOOD recommendation)
  • At least 3 SATA ports so that I can carry my drives over
  • At least one M.2 port (I cannibalized a laptop I recycled recently and grabbed the 1TB M.2 card)
  • On-board Ethernet/NIC (on-board wifi/bluetooth not required, but won't complain if they have them)
  • Support at least 32 GB of RAM
  • GPU that can support some sort of ML/AI with DisplayPort (preferred)

Nice to haves:

  • MoBo with front USB 3 ports but will accept USB 2 (C vs A doesn't matter)
  • On-board sound (I typically use headphones or bluetooth headset so I don't need anything fancy. I mostly listen to music when I code and occasionally do video calls.)

I threw together this list: https://pcpartpicker.com/list/n6wVRK

It didn't matter to me if it was in stock; just wanted a place to start. Advice is very much appreciated!

EDIT: WOW!! I am shocked and humbled by the great advice I've gotten here. And you've given me a boost in confidence in doing this myself. Thank you all and I'll keep replying as I can.

  • Some thoughts:

    Ubuntu, most likely

    I'd encourage you to take a look at Linux Mint, it alleviates some of the Ubuntu fuckiness. And if you want to join the "I use arch btw" crowd, maybe checkout EndeavourOS if you're feeling more brave than just Ubuntu variants (which is built on arch, but makes barrier to entry a little easier).

    i9s are the latest hotness but don’t think the price is worth it

    Take a look at last generation to soften the blow to your wallet. E.g., instead of looking at a 14900k, look at 13 or even 12 series. In fact, this is a useful strategy all around if you're being price conscious: go one gen older.

    GPU that can support some sort of ML/AI with DisplayPort

    Probably going to want to go with a discrete card, rather than just integrated. Other major consideration is going to be nvidia vs AMD, for which you'll need to decide if CUDA should be part of your calculus or not. I'll defer to any data science engineers that might wander through this post.

    The rest of your reqs pretty much come as regular stock options when building a pc these days. Though another nicety for my latest builds, is multi-gig nics (though 2.5Gb was my ceiling, since you'll also need the network gear to utilize it). Going multi-gig is nice for pushing around a fuckton of data between machines on my lan (including a NAS).

    Very last thing that I've found helpful in my last 3 builds spanning 15 years: I use newegg for its reviews of items, specifically so I can search for the term "linux" in any given product's reviews. Often times I can glean quick insight on how friendly (or not) hardware has been for other's linux builds.

    And I lied, I just remembered about another linux hardware resource: https://linux-hardware.org/?view=search

    You can see other people that have built with given hardware. Just remember to do a scan too once your build is up to pay it forward.

    Good luck, and remember to have fun!

  • For AI/ML workloads the VRAM is king

    As you are starting out something older with lots of VRAM would be better than something faster with less VRAM for the same price.

    The 4060 ti is a good baseline to compare against as it has a 16GB variant

    "Minimum" VRAM for ML is around 10GB the more the better, less VRAM could be usable but with sacrefices with speed and quality.

    If you like that stuff in couple of months, you could sell the GPU that you would buy and swap it with 4090 super

    For AMD support is confusing as there is no official support for rocm (for mid range GPUs) on linux but someone said that it works.

    There is new ZLUDA that enables running CUDA workloads on ROCm

    https://www.xda-developers.com/nvidia-cuda-amd-zluda/

    I don't have enough info to reccomend AMD cards

    • I got ROCm to work on a 7800XT after fixing some Python errors. It was quite unstable though.

  • Honestly any parts you buy today probably won't be much good in 30 years.

  • I'd defintely go with an M.2 SSD, you can get 1tb for 50€ and 2tb for 100€ now and they're much faster, more reliable and take up way less space.

    For ML/AI stuff, you might be just fine using an AMD GPU. AMD GPUs are a lot easier to use on Linux and are also a good bit cheaper. I use Fedora with an AMD GPU and I just installed the packages for OpenCL and HIP and now I can run LLMs on my PC using my GPU. I've also used Stable Diffusion with that GPU on Linux before. If there's something specific you want to do regarding that, I'd look up first if you need an Nvidia GPU for that but from my experience AMD GPUs work just fine.

    I'd take a look at AMD CPUs again. Last time I checked they were even cheaper (including mobo price) than Intel even though they're also more efficient (faster and less power draw). Prices might have changed tho. You should probably use a Ryzen 5, a Ryzen 7 will only make sense if you use all cores because game performance is pretty much the same. A Ryzen 3 is more of a budget option tho, I wouldn't use that. If it's in your budget, you should also use the newest generation that uses the AM5 socket because you'll be able to upgrade your CPU without needing a new mobo. I think it also only supports DDR5 RAM, which is more expensive than DDR4. If you use a Ryzen generation that uses the AM4 socket, it's gonna be cheaper but if you want to upgrade you'll need a new mobo with AM5 and new DDR5 RAM in addition to the new CPU.

    As for Linux distros, my recommendations are Linux Mint if you want something very easy, EndeavourOS if you want something Arch-based or Fedora if you want something that's not quite as easy as Mint but more up-to-date. I personally use Fedora but I used EndeavourOS before. I detailed why I switched to Fedora in a reply here somewhere.

  • I for one would not purchase any Intel hardware as long as AMD is around. Not that they're bad or anything, but AMD gives me much Kore "bang for the buck". To future proof your rig, I strongly suggest you go with the latest socket (be it Intel or AMD, doesn't matter) and make sure you get DDR5 RAM. PCI Gen 4, and then have at it.

    Getting an 80 Plus Gold power supply is always nice too.

    And then there's the cooling. I see you went with a radiator and fan, but I strongly suggest getting some type of liquid cooling. The prices are not that bad anymore (unlike about 10 years ago, which was insane).

    As for the board, you'll get all kinds of different suggestions. Some people swear by Asus, I'd rather go with Gigabyte (love the Aorus line), so it'll come down to brand trust at the end of the day.

    As for the card, I hear a lot of crap given to Nvidia about being closed source, and I sort of agree that's messed up, but ATI cards (while pretty good) are always a step behind Nvidia. Plus, most distros have them working out of the box.

    It can be intimidating after so many years, but its way simpler than it was back then.

    Good luck man, you got this, there's nothing to fear but fear itself.
