Make a $350-$550 mini server rack for $70!

Let's say you have some rack-mountable servers in your house. For example, you might have a web server for your corporate website, a file server for your terabyte of (un)pirated media, and sundry networking equipment. Let's say all of this gear totals 8U, or about 14" of vertical height.

If you're like my housemates and me, then the obvious thing to do would be to purchase a hulking, steel 42U (over 6' tall) server rack and put it in the the entryway of your house.

After a few years of cohabiting with the 42U monstrosity, we decided that it should be replaced with a smaller, 12U server rack. Ben decided to price this out and found this one ($565) and this one ($341). We looked at these racks, then at their price tags, then back at the racks, and then realized that we were about to drop hundreds of dollars on a glorified end-table.

So, why not just use actual end tables?

Hence, this Instructable. In a nutshell: epoxy together two of IKEA's CORRAS bedside tables. Two are needed because each is only about 15" deep, and most rack-mount servers are 20"-30" deep. The project is pretty simple because these end tables just happen to have exactly the right inside width to fit servers. They even come with handy shelves to set the servers on.

A few photos of the finished product are below (apologies for the crappy mobile phone photos, throughout; it's all we had on hand at the time):

Thanks for the idea. However, I had noise as an extra problem, so I had to add acrylic glass doors and active ventilation. No extinguisher yet, but at least some fire alarm...

Good ikea rack
thats a good idea.

Sweet, thanks for that!
what is the internal width of the eina table?

Great 'ible!!  I want to comment on your awesome style of being informative AND entertaining.  I have to remember to make my next one more fun.

You came up with a great solution to a problem I've been thinking about for some time.  Thanks again!

what is the specs of  your server?
ethosrot5 years ago
Absolutely beautiful.

A few friends and I are looking at putting together a 16U rack from scratch for some projects we have, and I was curious if anybody had already done it on here. Unfortunately, there is no IKEA near here, so this is not really feasible for me. Great instructable though!

Back to Home Depot for me :D

This is a pretty cool project but, I can't help but think about how deafeningly loud those rackmount servers would be in my living room. Especially with hardwood floors. What can you do to quiet this system down? Can it be inclosed instead of left open? Can you add sound deadening foam?
nagutron (author)  WAFexpert5 years ago
Hey, thanks for reading. Yeah, it is a bit loud, but luckily our server lives in a hallway, away from our bedrooms and kitchen/living areas. I'm not sure how to sound-proof something like this; sound proofing is really difficult when you also want good ventilation.
Well, for $50 or so, you can pickup some sound deadening sheets to stick to the insides of the cases or perhaps inside the enclosure and some sound deadening foam blocks to stuff stuff inside the empty 3.5 and 5.5 inch drive bays. Which in some ways and increase airflow and improve cooling but, I don't know how effective it would be. All of the know alternatives are incredibly expensive. Pretty much starting at $600 and going up to and beyond $3,000 (depending upon the size of the enclosure (6U to 42U). I'd be really curious to see what could be accomplished for under $150 (or twice the cost of the original enclosure; or less).
Cool server rack, I guess I will be out of a job soon then...how can my enclosure cabinets compete ;)
nagutron (author)  Server_Rack_Guy5 years ago
Well, as you can see from the comment below, noise is certainly an issue with this homebrew setup. But otherwise, yeah. These are working quite well for us.

Wow in that picture of your friend standing on the rack he looks just like Nicholas Brendon

I just saw this: an industrial-strength server rack built out of a Helmer filing cabinet. This guy was using it to create Linux server cluster for 3D rendering. Pretty awesome.

Nice. Are PC servers the same dimension as most rack mount audio equipment, 19 inch? I would like a more furniture like rack for my sampler collection.
nagutron (author)  bustedit6 years ago
Yeah, 19". This should work great for rackmount audio gear, too. Good luck!
thanks. i sent that ? before i read the final step. IYO is that faux wood strong enough to hold heavy equipmnt if only secured to a metal rack that is epoxied to the cabinet? im worried about torsion stress, as most kit is only supported by 4 screws at the front.
nagutron (author)  bustedit6 years ago
Yeah, I don't think it would be strong enough, either. Our setup works because we simply stacked stuff with rails in between for airflow. The shelf provided some separation. If you really need to be able to quickly add and remove components without disturbing the stack, this setup isn't ideal. We almost never need to move things around, though, so this was perfect for us.

Great writeup! I just got myself a Dell server and was looking for a rack for my home... Nothing 42U big, just something to keep it from being stored on a table or on the floor. After seeing that even for an 8U rack it costs almost $500 (rounding); I found this... can't wait try it out! I'm going to take that idea also to drill some vent holes on the shelf as well as maybe on the sides. For a couple of servers, I can see this as very cost effective. You can even go as far as putting some fans in at the top to vent air out that way too.
nagutron (author)  genenius6 years ago
Nice. Post some pictures if you do do it; I've to see what variations you come up with.
danlocks6 years ago
As long as you're using epoxy, you could common trick used to repair delamination in boat hulls: drill your holes through the veneers. put tape over the bottom hole. mix up some epoxy (the thin runny boat kind works best) and fill the cavity. Now drain most of the epoxy out. Doesn't matter too much if you drain all or a little, you were just trying to coat the inside of the cavity with the thin stuff. Thicken the epoxy with something (sawdust, We$t Marine Filler #50456098..., flour??). Cover the bottom hole with tape again. Fill the cavity with the thickened epoxy and wait for it to set, say, overnight. Re-drill your holes and you have a strong surface for the bolts to bind against w/out crushing the paper or twisting the veneer.

That's a great tip, danlocks. Thanks.

Hi there, I'm about to build one of these and I was just wondering how it was holding up for you heat/vent-wise.
nagutron (author)  srwoodruff7 years ago
It's been doing just fine. All of our equipments vents front-to-back, so constriction around the sides doesn't seem to be a problem. Also, the hottest components (the web server and the Dell file server) are separated. The rails along the bottom surface lift the Dell, too, allowing for some airflow. If you're concerned, you can add spacers or even cut large vents in the shelves. I'd love to see how yours turns out. If you get around to making one, post a pic!

wow.. ya.. token rings... that was the most pointless thing i learned in my networking class i took. besides everything else around the same time. wait a seconds... that whole class was about obsolete networking.... i want my money back.. damn online expert....
Token ring networks were all the rage among computer scientists. FDDI even got pretty far in the market before they got heavily trampled by the engineering behind real networks and ethernet implementations. "with a gaussian distribution of packet sizes a 4 Mbit token ring should out-preform 10Mbit ethernet." "But my packet sizes don't have a gaussian distribution of sizes and my ethernet card was 1/10th the price of your token ring card!" "Oh."
It's not useless if it wins you a prize in Anything but Ethernet! ;) Seriously, there's still a lot of legacy Token Ring hardware out there, especially in legacy IBM shops, and there's no harm in knowing how it works, and especially how it fails. Kick the MAU!

The Token Ring is just that much funnier because it's inches away from a GigE switch. It's gratifying to know I'm not the only one with a hardware collection like that.

A token ring concentrator? Even the cisco labs, bastions of ancient technology that they are, have been throwing those away for years now!
nagutron (author)  westfw7 years ago
Note that there are no LEDs active on that thing. It's there simply to impede airflow over the file server :)

$70? i guess it looks pretty, but would could have gone way lower
nagutron (author)  theRIAA7 years ago
We considered making the cabinets ourselves. The basic shape of the thing is really simple, after all. But my housemate was tossing these end tables out, so we used them. Really, for us, this was the $10 IKEA Mini Server Rack. But yeah, it looks nice, too.
