I placed a low bid on an auction for 25 Elitedesk 800 G1s on a government auction and unexpectedly won (ultimately paying less than $20 per computer)
In the long run I plan on selling 15 or so of them to friends and family for cheap, and I’ll probably have 4 with Proxmox, 3 for a lab cluster and 1 for the always-on home server and keep a few for spares and random desktops around the house where I could use one.
But while I have all 25 of them what crazy clustering software/configurations should I run? Any fun benchmarks I should know about that I could run for the lolz?

If I had 25 surprise desktops I imagine I’d discover a long dormant need for a Beowulf cluster.
The thought did cross my mind to run Linpack and see where I fall on the Top500 (or the Top500 of 2000 for example for a more fair comparison haha)
Shitty k8s cluster/space heater?
God damn. What are the specs on those? I gotta check out some government auctions.
4th gen intel i5s, 8GB of RAM and 256GB SSDs, so not terrible for a basic Windows desktop even today (except of course for the fact that no supported Windows desktop operating system will officially support these system come Q4 2025)
But don’t get your hopes up, when I’ve bid on auctions like this before the lots have gone for closer to $80 per computer, so I was genuinely surprised I could win with such a low bid. Also every state has entirely different auction setups. When I’ve looked into it in the past, some just dump everything to a third party auction, some only do an in-person auction annually at a central auction house, and some have a snazzy dedicated auction site. Oh and because its the US, states do it differently from the federal government. So it might take some research and digging around to find the most convenient option for wherever you are (which could just be making a friend in an IT department somewhere that will let you dumpster dive)
They’re actually decent. Congratulations!
Setup a CS 1.6 LAN party arena.
No pen testing lab sounds fun. 8 PCs for a segmented network, a few red team PCs.
Run 70b llama3 on one and have a 100% local, gpt4 level home assistant . Hook it up with coqui.Ai xttsv2 for mind baffling natural language speech (100% local too ) that can imitate anyone’s voice. Now, you got yourself Jarvis from Ironman.
Edit : thought they were some kind of beast machines with 192gb ram and stuff. They’re just regular middle-low tier pcs.
I tried doing that on my home server, but running it on the CPU is super slow, and the model won’t fit on the GPU. Not sure what I’m doing wrong
Sadly, can’t really help you much. I have a potato pc and the biggest model I ran on it was Microsoft phi-2 using the candle framework. I used to tinker with Llama.cpp on colab, but it seems they don’t handle llama3 yet. ollama says it does , but I’ve never tried it before. For the speed, It’s kinda expected for a 70b model to be really slow on the CPU. How much slow is too slow ? I don’t really know…
You can always try the 8b model. People says it’s really great and even replaced the 70b models they’ve been using.
Show as in I waited a few minutes and finally killed it when it didn’t seem like it was going anywhere. And this was with the 7b model…
It shouldn’t happen for a 8b model. Even on CPU, it’s supposed to be decently fast. There’s definitely something wrong here.
Hm… Alright, I’ll have to take another look at it. I kinda gave up, figuring my old server just didn’t have the specs for it
Specs? Try mistral with llama.ccp.
It has a Intel Xeon E3-1225 V2, 20gb of ram, and a Strix GTX 970 with 4gb of VRAM. I’ve actually tried Mistral 7b and Decapoda Llama 7b, running them in Python with Huggingface’s Transformers library (from local models)
These are 10 year old mid range machines. Llama 7b won’t even run well
The key is quantized models. A full model wouldn’t fit but a 4bit 8b llama3 would fit.
It would fit but it would be very slow
No. Quantization make it go faster. Not blazing fast, but decent.
According to Bush Jr. And Cheney you are now capable of building a super computer dangerous enough to warrant a 20+ year invasion
Depending on the actual condition of all those computers and your own skill in building I’d say you could rig a pretty decent home server rack out of all of those for really most purposes you could imagine, including as a personal VPN, personal RDP to conduct work on, personal test server for experimental code and/or testing potentially unsafe downloads/links for viruses
Shit you could probably build your own OS that optimizes for all that computing power just for the funzies, or even use it to make money by contributing its computing power to a crowd sourced computing project where you dedicate memory bandwidth to the project for some grad student or research institute to do all their crazy math with. Easiest way to rack up academic citations if you ever want to be a researcher!
What are you referencing in regard to the super computer investigation? Internet search failed me
https://www.ign.com/articles/2000/12/20/iraq-scores-hordes-of-ps2s-at-us-gamers-expense
I’m pretty sure this is it.
Weird. Thanks for finding it!
So on one I would suggest frigate. Those support (I think) and pci-e coral ai chip.
Home assistant would be great bare metal
If I were you I might try deploying a mini enterprise network with permissions and things. It would be fun to do it with active directory to try to practice pentesting, or it would also be fun to do with linux to try to learn more about deploying linux in enterprise environments.
This is pretty high on the to-do list. I plan on virtualization a bunch of it, but it would be pretty easy to have one desktop hosting each subnet of client PCs and one hosting the datacenter subnet. Having several hosts to physically network means less time spent verifying the virtual networks work as intended.
Also playing with different deployment tools is a goal too. Having 2-3 nearly-identical systems should be really useful for creating unified Windows images for deployment testing
I don’t like windows, so I don’t deploy any of this for real, but yesterday and the day before I set up a windows server, a few clients, and a Kali VM and manager to get in. I found out if you type “\\anything” into the windows bar it will send that user’s name and hash out very easily with llmnr poisoning on every keystroke. What’s worse is that is the default behavior. It is super fun to learn about all this though.
Edit: upon posting this comment it made the double backslash look like a single backslash so I changed it to a triple so it looks right on my end but just know I meant for it to be double.
BOINC! Do some science. :)
a pallet of 4th gens? i have a dozen left here from around that era that i can’t get rid of without literally giving them away. they’re ‘tolerable’ for a gui linux or win10 with an ssd, but the ‘performance per watt’ just isn’t there with hardware this old. i used a few of them (none in an always-on role, though), but the rest just sit in the corner, without home nor purpose.
these 800 g1s are, iirc, 12vo, so upgrade or reuse potential is a bit limited. most users would want windows, and win10 does run ‘ok enough’ on 4th gen, just make sure they’re booting from ssd (120gb minimum). but they’ll run into that arbitrarily-errected wall-of-obsolescence with trying to upgrade or install win11 when win10 retires in ~ 18 months (you can ‘rufus’ a win11 installer, but there’s no guarantee that you will be able to in the future). that limits demand and resale value of pretty much all the pre-8th gen hardware.
They are fine honestly. It depends on your expectations
I think you’re not giving 4th gen enough credit. My wife’s soon-to-be-upgraded desktop is built on a 4th gen i5 platform, and it generally does the job to a decent level. I was rocking a 4790k and GTX970 until 2022, and my work computer in 2022 was on an even older i5-2500 (more held back by the spinning hard drive than anything. Obviously not a great job, but I found something much better in 2022) my last ewaste desktop-turned-server was powered by an i5-6500 (which is a few percentage points better performance than the 4th gen equivalent) and I have a laptop I use for web browsing and media consumption that’s got a 6700HQ in it.
I’ve already got a few people tentatively interested, and I honestly accepted the possibility of having to pay to recycle them later on. Should be a fun series of projects to be had with this pallet of not-quite-ewaste
The i5-6500 is my favorite CPU
If you purchased them from the federal government they won’t have hard drives.
State government, and it says they come with SSDs. They came from a school so presumably they’re from a lab or are upgraded staff PCs, both would be pretty low sensitivity. Maybe I’ll learn the final test answers for Algebra 1 at worst!
Might be fun to do some forensic data recovery and see if anything was missed though
Ooh, or behind the scenes email drama from staff!
Xonotic!
Do you have particularly cheap or free electricity?
12 cents per kilowatt-hour. I certainly don’t plan on leaving more than a couple on long term. I might get lucky with the weather and need the heating though :)
I think the only answer is “Doom”
But can they run Crysis?
We’re you thinking like Doom Lan party, or some weird supercluster with the pure focus of running Doom?
If OP actually does do this I recommend Odamex
Although he’d also need 25 monitors lol
Back to the government auctions then!
