honestly, systemd isn’t that bad. I’m finishing some free labs for the CompTIA Linux+ sysadmin course and learning how to compose bash scripts into services is going to be great for my homelab.

I completely ditched windows at home in early 2020 and used fedora until last year when I took the plunge into NixOS. I knew how to do things in Linux, but I wanted to understand the underlying system structure. NixOS helped pull back the veil a bit.

Using NixOS was when I finally felt like I started to understand Linux. I don’t think I could go back lol

I’m using a surface laptop studio with the linux-surface kernel (NixOS, btw :p).

It’s actually quite repairable compared to some other offerings and are generally available used on ebay. I won a $610 bid for mine with an i7, 32gb RAM and a 3050ti. I think all the models have the same 120hz 3:2 screen too. I’m incredibly pleased with it.

If using Linux is wrong, I don’t want to be right.

I appreciate the kind words! Until recently, my day job was CAD monkey. I wanted to consolidate the hardware I was cobbling together, found a cheap 8 GPU mining rig and some extra 2020 extrusions to play with.

The seller for the mezzanine said it followed the mATX mounting hole pattern, (it does but is ~75% in the width and doesn’t use all the points). I have a tendency to overthink designs and kind of stalled for a bit before finally taking the plunge and whipping up these struts. I used some brass heat set inserts to accept the standoffs and everything pretty much went right together lol

I am using PTM sheets and they idle at decent temps, though I did ziptie some high CFM fans behind them lol

eBay has some rad Chinese mezzanine boards for these guys too. Nvlink works and everything lol

Yeah I mean I don’t know the rest of the story I guess. Like, maybe there’s a perfectly good reason that they’re doing what they’re doing 🤷

Plus like, i might not mind 👀

I’d be worried looking might be interpreted as leering or being otherwise disrespectful.

I bet you used a keyboard, instead of a magnetic needle and a steady hand to code this too.

For real though, nice work. 🎉

“the front fell off?!”

They’ve been temporarily removed for about a year now lol

I’m actually quite happy with it. It’s a 24gb p40 which runs some of the older LLMs quite well. Repasting with liquid metal helped thermals a ton too

It’s a Tesla P40 24gb I got off eBay a while ago. Just like AllHailTheSheep suggested, it’s a server GPU meant for compute workflows so it relies on forced air from a server rack. I repasted the die with liquid metal and added a 3d printed duct to attach the radial blower to. The thing never cracks 60c under inference which is nice. Idles around 24c

(Edit: I’m mostly using it for LLMs, but it supposedly makes a good CAD card, so I might give that a shot too)

Thank you 🥹 It’s been quite the experience lol

I thankfully snagged this one pretty cheap off eBay. It’s actually an 8-gpu mining rig frame that conveniently fit my CEB motherboard lol

My janky homelab lol. Mostly ebay secondhand Enterprise stuff and a Chinese SXM2 mezzanine board to run dual NVLinked 16gb V100s. I also have a TrueNAS Scale mini itx server running upstairs with my “arr” stack and some other useful tools.
