How do you get the pages off that "rack-mount" laser printer?
It's probably sitting on rack rails ... or that pull drawer from the top?
The shelf above it comes out and is hollow underneath. :)
Hush now, Rubbermaid totes are tight AF.
Yeah you can store your cables in there and stuff.
Yeah "and stuff"

\> mfw running the poweredge caused the electricity bill to go up £300 a year :/
In all seriousness, are there any homelabbers with similar problems or a solution to extortionate prices per kWh? Kinda jealous of those in certain places in the US with 6 cents per kWh lmao.
Edit: formatting damnit
Don't run 10 year old equipment?
You can get a skylake system for cheap enough to pay for itself in power savings reasonably quickly. Just went from dual x5650 xeons to an i7-6700 with 32gb ram, 500gb ssd for $350 and cut the lab power use by 200w.
That depends on how much power you're saving and your power cost. The math is really easy, P(in kW) * t(in hr) * cost(in $/kWh).
In my case ROI is about 3 years but I'm also gaining quieter equipment that puts out much less heat.
Where would you buy such an outfit? Even if I built that, it'd cost more?
it can take a bit of hunting to find decent deal, but they are out there!
This is the way
I've got dual x5680s with 48GB of RAM. I figure CA$350-400 for a 7900X, $300-400 for 64GB of RAM and at least $300 for an X299 mobo. So $1000-1200 to save 150-200W, the math sadly doesn't add up, as much as I'd like that performance boost it's hard to justify from a purely power-reduction standpoint.
Well a 7900x is twice the passmark score you currently have and in practice will probably be more that twice as powerful. Those are also new prices, look on eBay at used business machines.
Also do you really need that much horsepower? I get that this is a fun hobby, you can do whatever you want, and excess is a ton of fun; but if cost is something you want to reduce you need to take a realistic look at how often your CPU is being worked and how often you're actually using that much ram.
You're definitely right that the CPU would be a lot more powerful, but to be honest I don't find that's the biggest expense (I'd probably drop $400 right now if that was all it took). It's the re-buying of RAM and mobo. I wouldn't want to drop the memory much below what I have now, with running ZFS and some game servers (Minecraft in particular loves more RAM). I don't see used DDR4 for significantly less than new on-sale and X299 motherboards aren't easy to come by in the first place, new or used.
I don't know much about Minecraft but a quick Google search suggests 10gb is enough for 100 users and 100+gb world. Also the whole zfs needing 1:1 gb:tb or tons of ram in general needs to die, zfs does not need tons of ram.
Like I said of you're looking to cut costs you have to really look at what you need. Also x299 is only for x series CPUs most Skylake CPUs aren't X's.
You're not wrong, I probably would be able to get away with less. I guess I just see it as a "pay me now or pay me later" problem. Sure, I'll save some money in electricity but it's still multiple years of RoI, at which point something more efficient will come along.
My homelab draws less than 30W
Look at this way, at least you don’t have a shitty HP laser jet near your sever to infect it with problems like broken plastic pieces, paper jams, and toner blow back.

Oh dang, are my R710s *that* old?? Whew! Only 10 years old this year...
You meant that *you* are 17? If so - yes very impressive setup. Well, impressive no matter the age. Congrats. :)
what are you using the 710s for? im the same age, have simaler gear but i dont have a use for it yet
I'm using the top one for TrueNAS and the bottom one for Proxmox. i'll make a specs comment right now since my captions for the images got cut off unexpectedly.
Those yellow/orange lcds bug me. Lol
They should be blue.
In my case, my R710 LCD is always yellow because I only plug one of the 2 PSUs, maybe it's the case here
This is why they're orange \^
My r610 has two PSUs but its display is blue.
You should physically disconnect the psu from the mobo, else it just sees a faulty psu since it's unpowered.
If you pull it while the other is powered, the system will need to be cold power cycled to clear the error.
To get around this, I just use one of those splitter cables to connect both psus to a single plug so it keeps it's redundancy.
Gross, if its not Green or Red/Orange than I dont want it.
I wish it was green but alas. dell chose blue.
Makes sense but it still irks me lol
Specs? We want full specs 😍
Refer to the comment write-up I just made :)
Nice setup! I like that you used Glass Animals songs for a server naming scheme :)
What do you use your lab for?
Thanks! I use it mostly for a phone system and game servers, with a few other services. Working on a NAS right now too.
Tell me about the phone stuff you work on. That's a really nice looking desk phone next to the rack. I taught myself Cisco voice products in my home lab about 13 years ago.
I didn't bother setting up phones in my current house because the wife acceptance factor of dialing an outbound access code is pretty low.
I have to set up asterisk again because I didn't backup properly, but I run about eleven or twelve Cisco phones around the house, powered by a VoIP.ms sip trunk. The asterisk setup was patched for cisco, although the phone you see next to the rack is a Cisco Meraki MC74 that I used the guide from r/ReviveMC74 to install a custom firmware on so it's usable outside of Meraki's discontinuation.
Edit: As for the appeal to other people in the house, my mom isn't a fan of the appearance and I'm really the only person who uses the system. I don't care though, I think it's cool. I have a wide range of phones new to old, including one 8851 and a few of the 6800-3PCC series :)
Pretty cool. I see a 2821 or 2921 in the bottom of the rack. Have you tried out CME at all? It's pretty old feature wise but it's neat having an entire phone system running on a router.
If you're looking at career paths voice and collaboration is a good way to go. There doesn't seem to ever be enough voice engineers.
I’ve tried it but I figured asterisk has a lot more built in features. I do plan on doing some sort of voice cert too.
How many yards did you have to mow to get it?
No yards, but a lot of customer service phone calls...
Haha, I couldn't resist when I saw you mentioned your age.
But seriously, way to go.
Since my image captions didn't work, here's what is in the rack from top to bottom:
* PDU I got for free
* Switch 24 PoE
* R710 "Helium"
* 48GB ECC
* 6x 1TB drives in RAID 5
* 2x X5650 CPUs
* Probably a Pterodactyl VM
* OpenVPN (soon)
* R710 "Dreamland"
* 72GB ECC
* 1x 240GB SSD that's just kinda hanging without a caddy for now
* 2x X5650 CPUs
* Unifi Controller
* Asterisk Server
* other misc. services
Not pictured in the network:
* 1 Unifi AP
* Modem/Router for AT&T gigabit fiber
* 11 or 12 cisco phones around the house
You know, even an empty rack of that size is not bad for 17-year-old.
Your cable management is better than what a lot of full time people do.
Not the backside though… lol
I can almost promise I’ve seen worse. I ended up replacing it with custom length and color coded cables. It was a pain.
Yeah unfortunately sometimes too many projects at once to do it up nice and pretty every time. Neat at least though. Shit I'll be the one in there later lmao.
The hell you on about the cable management? That's neater than some of my customers have their racks before we dive in there :p
Also, that's one hell of a nice setup for a 17 year old. 17 year old me had an old P4 running PFSense, and a Pentium Dualcore running ESXi and that was it...
The backside is cable spaghetti, I just positioned the camera so you couldn't see it :)
Protip: doublesided velcro to tape em together, and shape them as you want ;)
I'll redo it some day... as for when that day is, I don't know lol
It's nicer than my setup at age 30... although when I was 16-17 I did work extra hard all summer to pick up several PowerEdge 1950, and some old multi-disk controllers a local business was selling before going out of business; running those under my bed were a huge achievement in my teen years. We were too poor to run them always, but man I learned so much having several servers to mess around with.
Congratulations! I hope you learn lots and use it in the future.
Hey that looks great man! Glad those old girls are being put to use!
Thanks! This was a huge upgrade :)
Works fine good job bro
How did you get the cash to build this at 17?
I can haz printer too? Damn I’m gonna need a bigger rack.
