Did you forget to add cross-braces [0]? Ivar has always been rock-solid for me. [0] https://www.ikea.com/us/en/p/observatoer-cross-brace-galvani...

Even with cross bracing it had too much wobble, which would pull the short pins out of the cross board, and if you bumped a shelf it would hop out and then fall.

That sounds like you didn’t properly clip the shelves on (it takes a bit of force). In any case, that’s not how Ivars usually behave.

Used rackmount equipment can be had for cheap when businesses decommission them. The depreciation curve is much sharper than typical consumer gear when it goes out of support. New rackmount gear is very expensive. Many people who have home servers (me included) buy used enterprise gear for this reason.

How would you suggest going about buying used enterprise gear? I was thrilled to get a decommissioned optiplex and old monitor from an old job, but that's just because I happened to be in the office the day the stuff was lying around. Otherwise I have no idea how to get that kind of stuff

It's typically ebay for me, possibly craigslist as well if you live in a big city.

For all the effort (and money) put into making a media server as quiet as possible (which is still not silent), I think you're way further ahead to just not put the server in your living room. Instead, put it in the basement/closet/garage/utility room -- somewhere you won't hear it. Then, broadly speaking, you have three options: A commercial box, like NVidia shield, Chromecast, Roku, Amazon Fire stick or AppleTV. Th…

I put a rack/cabinet in the laundry room, with a QNAP NAS in there, Plex server is running on the QNAP, then an Apple TV 4K connects to that and feeds the TV. I like this better than trying to do some sort of long HDMI cable setup, because the HDMI ports on most NAS units out there get old rapidly, don't support HDR and high bitrates reliably, etc. This way, it doesn't matter if the server is brand-new and fast enoug…

I have a similar setup myself. I use basically an older PC running Proxmox + openmediavault as my NAS (and a bunch of other things, including Plex). I currently have an NVidia Shield and 'Chromecast with Google TV' as clients, as well as a couple phones and tablets. It is pretty hands-off and my family can all use it just fine.

I'm content to replace the relatively cheap client boxes every few years. That said, I think I've had the Shield for over 5 years now and other than the original remote being bent in half (likely a jumping-on-the-couch-related failure) it's still going strong.

I have been really happy with the HEJNE shelf as a rack. Here are some 2U's here at home: https://s3.whalesalad.com/lab/rack.jpg The shelf: https://www.ikea.com/us/en/p/hejne-shelf-unit-softwood-s7903... I keep seeing full height Dell racks for sale on FB marketplace in the $200 range but haven't encountered the right manic episode to actually go for it.

It's not the rack that's the problem, it's the fans. Most industrial gear requires a ton of airflow and the noise is something like having a model jet engine sitting in your closet. This from someone who actually did go for it and later recanted.

This is a good point for why an actual rack is a bad thing for some use cases in the home. When moving into my current house an AV Geek neighbor setup a home theater type setup with the receiver, amp, in house audio (VSSL) amp, and other devices in a large high quality rack that I spent too much money on.

None of this uses a lot of power or makes a bunch of heat. The receiver tops out at 140W total RMS over seven channels and the VSSL is about 20 per channel. The rack adds an additional 75mm to each side of the rack and 120mm to the front and back. It takes up a lot of room in its closet and I’d be happier with more space to move around it.

LACKs are a bit too flimsy and small for the setup I want to replace. The parent’s shelving unit example looks like a great replacement, especially since I want to store things in that closet on shelves anyway.

HEJNE is "ok" but really REALLY add the cross bracing, and perhaps even add plywood to one side. I have a HEJNE that is just holding LEGO with cross bracing and it is visibly leaning. I don't expect it to fall down but I'm also not loading thousands of pounds into it.

I was wondering about this, I had a bunch of these screwed in together as a cheap kitchen cabinet when I was younger. They can be get pretty wobbly even with the braces.

I have a dozen of these tied together, with the cross bracing, into an L in my basement. The whole unit has a few ties to the cinderblock wall behind it. That arrangement adds a good bit of stability. I agree that a on their own or in small numbers they’re not very stable.

I prefer the minimalism of a "vertical rack" which, for some reason, I tend to never see. If you don't have more than 6U or so of equipment, it's really the way to go because of its minimal profile and amazing load-bearing ability: it is load-bearing parallel to the direction of gravitational pull (vs regular rack cabinets where the load is perpendicular to the posts), and then that weight is all redirected towards t…

Huh, vertical rack like that reminds me of immersion coolers for servers.

Yep. Used to run two gargantuan floor-to-ceiling racks, but they're just impractical. Over time, hardware gets smaller and smaller, and rack-mount gear is less and less common, mercifully. I have 12U of rack space left in my desk for fanless devices such as AD/DA convertors and compressors, 500 series, Eurorack etc. I would never want to go back to having huge racks, it's very impractical.

I always think it'd be cool to have a server rack in my apartment until I powered up a server in my apartment and it far eclipsed the noise produced by the air conditioning from anywhere in the living space.

Doesn't have to be like that though. I've got a rack next to my desk and it's fine noise wise, though less fun during summer (no AC here)

I wonder if it would help to fill them with some high density expanding foam? (Using some form of resin would probably be prohibitively expensive).

Maybe snap/chisel the melamine off and replace with felt pads or something.

You're thinking about the ends? I made some end caps for Lack tables that you can 3D print. For when you shorten the legs. https://github.com/borud/ikea-lack-leg-end-cap
