I've mentioned this before, but my first CoLo server was from a friend that built servers for a good sized hosting company back in the late 90s. He built it from spare parts but had no case for it. He hung the mother board against a dry erase board from the mounting holes with zip ties. He had a PSU sitting on his workbench with cables feeding up to the mobo. IIRC, the hard drive was suspended on the wall as well. In that vein, anything can be a "rack" if you squint at it hard enough and maybe tilt your head a bit.
LackRack is cute in that it works and fits, but the real home datacenter is wire shelving - one of THOSE bad boys can support hundreds of pounds AND have good airflow (and sneaky cable routing!).
If you trawl auction sites for business liquidations, you can also usually pick up an actual rack for pennies on the dollar.
It doesn't even have to be a tech business; most random offices have a small rack in a closet somewhere with some networking equipment on it, and the whole thing usually sells as one lot to anyone with $50 and a screwdriver to remove the equipment from the site.
They're not hard to find as you say (you can even find them at scrap yards and such) - though then you can find the fun of getting the right mounting hardware to actually PUT things in the rack (and you get to learn the difference between telco racks (very common) and server racks (somewhat less common).
If you've accidentally purchased a telco rack it won't be ideal, but modifying it into a server rack is going to yield a better rack than a coffee table or bookshelf.
Yeah for a lot of things these days I actually prefer a telco rack, as you’re unlikely to be shelving giant rack mount chassis and UPS as much as you used to.
I keep wanting to build this but I have seen people talking online that they changed the legs and they are now hollow and not really suitable for this.
That has made me very cautious to use this for any serious amount of mounting.
Edit: Apparently there is a section on that page about it, but does not give a ton of confidence that it won’t give me a lot of issues.
I swear every year that passes it sounds more plausible that IKEA has a bunch of people chewing on wood and putting it together into furniture like they were building wasp nests. Their stuff makes frickin' papier-mâché look like a steel girder in comparison.
I have an old Lack (20 years) and while I've never used it as a rack, it'd just been retired from under the TV as I got a new one with a wider base. I notice that even though it's never been moved much, it doesn't feel very stable any more and I wouldn't trust it with a rack of heavy equipment, especially with HDDs that could suffer catastrophic failure if they fell. That said, attaching brackets would sure up the legs a bit. Ideally you'd want to attack brackets at the back as well I guess.
I also had a Billy sat next to it, and did similar to this (but again not racked), with all of my AV gear inside. The door was great, it'd make any status lights diffuse and so they wouldn't interrupt watching a film in the dark (and my old Sky box used to have annoying blue LEDs with an animation when playing back a recorded show), but at the same time remote controls still worked through the glass. Literally best of both worlds. I cut a big hole in the back for cables, which also served well for airflow. I considered adding a fan, but never needed it. I suspect there would be issues with negative pressure doing that though.
The tops of the posts are still solid. You could mount a single rack unit and be okay, but fully populating lack legs is not recommended. Cute way to hide a network switch, though.
One really good alternative to racks is a flight case with integrated 4U / 8U rack. They're meant for musicians transporting audio equipment, so can be a lot expensive, but they're nice with front and rear panels that pop off, and are very portable. The bigger ones (12U and 16U) often come with wheels too which is nice.
What can I say, I'm a Billy simp, there's one just behind me as I'm writing this comment and for about a year now I've been forcing myself to buy a new one to put it on the right-side of my current desk (sometimes I'm too lazy for my own good, as in this case). So just seeing Billy in the title and as the actual subject of the blog-post made me upvote the submission, apparently I'm not alone in this.
I’m a pretty mid around the house DIYer, and I commend the ingenuity. But will never understand someone going to the expense and hassle of buying a Billy and converting it into built-ins. Someone who can do the conversion is also capable of adding their own shelves at a fraction of the cost, and the product would be far more sturdy.
ikea furniture is surprisingly bimodal, either it's cheaply made stuff that doesn't last or it's startlingly solid and cleanly designed for a great price. don't think I've ever gotten something that was just okay.
Yeah, looks like the KALLAX is preferred, the BILLY does leave a bit of album hanging out. (Although I don't believe you need all of 13" for an album sleeve—perhaps closer to 12½". Still overhang though.)
I once worked in a hardware lab that used wire shelving for holding arrays of running machines, and a bad ground running through one chassis caused anyone who touched the shelf to get shocked by something very close to line voltage.
That shelf is more glue and fire retardant than it is wood. Its also really bad as a book shelf so it might still be superior in this role than the intended one.
It depends on the loading. If you've got it 9-12" high apart and are putting paperbacks on there... that shouldn't be a problem.
However, when the shelf becomes multiples of that, then people start putting hardcover volumes or laying the book flat and stacking them high within the shelf.
It won't necessarily fail, but it can substantially sag with heavier loads.
This is an issue for boardgammers who are after larger and heavier shelf spaces which is why the Kallax shelving is much preferred. I'll also note that Ivar shelving is solid wood rather than particleboard.
