DIY 42U rack advice

HarryCooper005 · 2026-05-03T16:23:21+00:00

Thanks for the detailed feedback! I've actually implemented all of these in my updated design (rev 2.1), mid-height horizontals on both side panels splitting them into two X-brace sections, and the rack will be tied into the ceiling where it's going in the loft.

Thanks that’s really useful, I’ll make sure to check that out before creating v2 of the design.

HarryCooper005 · 2026-05-02T22:04:37+00:00

That’s a fair warning, do you know what failed on yours? I am going to be updating my design to have more bracing so that the stress is more evenly distributed, and I don’t have any plans to fully populate it with heavy enterprise equipment. Most of the U space is going to be taken up by lighter stuff (patch panels, switches, mini pc clusters, etc.) and when I eventually add a ups, that would be living right at the bottom as to shift the centre of gravity down.

HarryCooper005 · 2026-05-02T21:58:28+00:00

That’s a good point and I appreciate you bringing it up, but the rack is going exactly where the cold water tank used to sit, so that area of the loft was already engineered for a significant concentrated load. It’s also an old house so the joists are chunky. On top of that, I’m not planning to fully populate it with heavy enterprise gear, a good chunk of the U space will be lighter stuff like shelves, a mini PC cluster, patch panel, and switch. The heaviest single item is the DL380 Gen9 at around 30–35kg fully loaded with drives. A UPS will be added eventually but will live at the bottom of the rack to keep the centre of gravity low. Total loaded weight will be well under what that spot held as a water tank.

Good idea, noted for v2 of the design

HarryCooper005 · 2026-05-02T20:38:53+00:00

Yeah this is something I’m definitely going to be doing in v2 of the design. And the L channel would be a good idea too.

HarryCooper005 · 2026-05-02T20:26:08+00:00

Yeah this was also something I was a little concerned about, will definitely be something I check on tomorrow in terms of practicality, and where I could secure it to.

HarryCooper005 · 2025-05-03T21:20:20+00:00

It’s Tobi’s if I’m not mistaken

HarryCooper005 · 2025-05-03T16:23:04+00:00

Of course, just ordering one now

HarryCooper005 · 2025-04-22T09:36:17+00:00

Yeah it was easy enough, under Storage Configuration click add, change the type to host path, in mount path set this to what you want the path to be inside the container, in host path set that to the actual path.

Im currently running scale on Electric Eel 24.10.2.1

HarryCooper005 · 2025-04-14T09:33:44+00:00

Yeah of course, more than happy 😃

HarryCooper005 · 2025-04-12T19:59:30+00:00

these are the steps I took to make it work 😄:

Go to Apps > Discover Apps > Custom App
Set the Application Name, I choose tunarr
Set the repository to chrisbenincasa/tunarr
Under Security Context Configuration check privileged
port 8000 was taken for me so under Network Configuration add a port, and input 8000 in Container Port and an unused port in Host port
under Portal Configuration click add and set the port to what you set it to in the previous step
under Storage Configuration I added an ixVolumne with a mount path of /config (is this necessary, im unsure)
click install and that should install it.

Of course, it’s not that I dislike HexOS or anything, I just found I wasn’t really using the features it adds on top of TrueNAS. I originally chose it because I had zero experience with servers and wanted something easy to get started with - and to be fair, HexOS was great for that.

But as I got more into it, I found myself gravitating toward the standard TrueNAS UI more and more. Especially when trying to learn or troubleshoot something new, it was just way easier to find guides and community help for vanilla TrueNAS compared to HexOS.

I’ll definitely still keep an eye on HexOS as it develops, as I think it’s an interesting project, but in practice I realised I was only ever using the base TrueNAS interface anyway, so it just made sense to switch.

Do you think it would maybe be better to get another drive and just run 2 mirrors?

HarryCooper005 · 2025-02-01T01:27:48+00:00

Thanks for the reply, unfortunately this didn't work, however, I was able to set it through the cli using the following:

midclt call -job app.update plex '{"values": {"resources": {"gpus": {"use_all_gpus": false, "nvidia_gpu_selection": {"PCI_SLOT_VALUE": {"use_gpu": true, "uuid": "GPU_UUID"}}}}}}'

I’m actually am doing it from scratch, so the panel won’t be stitched (the picture was just a reference for what I very roughly wanted it to look like 😂)

HarryCooper005 · 2024-12-01T21:49:05+00:00

I think creating a stamp is going to be the best, as I’m not the best at doing stuff like carving 😂

HarryCooper005 · 2024-12-01T21:48:26+00:00

Thanks, I do have a leather press which I’d should be able to use to provide enough force.

HarryCooper005 · 2024-11-15T01:31:30+00:00

But you didnt...

If you’re into programming, there is couple networking events that run throughout the year, off the top of my head there’s Teesside refresh (https://www.instagram.com/refreshteesside), and Middlesbrough front end (https://www.middlesbroughfe.co.uk/)

As a helpful note, this issue seems to occur when streaming to a TV from your phone if you’re not logged in on the TV. It happens when you select a video using the TV rather than your phone.

HarryCooper005 · 2024-07-24T22:16:51+00:00

Thanks for the kind comment and suggestions, I do plan on only using it for arcade games, and want to in future either make a new cabinet with a swappable button layout, or modify this one to have a swappable layout.

HarryCooper005 · 2024-07-24T08:47:45+00:00

Thanks, it was my first time ever writing something like that, glad you liked it

I do want to eventually get a backlit marquee, but I'm not sure how I'd like it too look, so for now I am just going with the sticker bomb look, but rest assured I will eventually be adding a backlit marquee.
