I shall leave the GUI running until I receive my pool payout tomorrow so I can move it to my cold wallet, and remove the drives and GPU from my server at the weekend.
A couple of drives will be used in my NAS which I use for off site backup, the others sold.
Another Chia warrior retires.
Good luck in your future ventures Ronski!
I’ve miniaturized my farm while steadily cutting TBs.
Here’s what’s left.
Best part is it barely uses any power 
Like most, I switched off my 700tb at the beginning of the summer. Haven’t had the heart to sell off yet, but soon!
It was a bit sad to be turning it off, but once done I felt better for it. I turned off 5 x 18TB USB drives early summer due to the heat.
It did seem unusually quiet when I came down this morning, no fans roaring away, which is also nice.
Used quite a bit less electric so far as well, should be even less when the hardware is removed.
Leave the GUI/pool sw able to run somewhere. I found a half a XCH after a week or so later on the pool, not sure where it came from, not worth much, but still.
It only feels bad to turn everything off, then it feels good, like a relief as you say.
You might plot just a few TBs to MMX, to keep busy, for fun, keep the mind fresh, and learn something new.
You never know, you may catch the bug. Worked for me, it’s loads better, far less power to farm & no need for a GPU, and has potential like the Mythical Phoenix…to raise from the crypto ashes…rather the the slow train wreck that is Chia.
I quit Chia 2 years ago but still farming. I am crazy but got 3.5PB in MMX and all I farm has no value at the moment. But usually early adopter win when decide to take a risk, the same was with Chia.
If you have (an) older CPU(s), you actually do need a GPU for the VDF part - but not much of one, GT1030 or comparable is plenty.
Since you have to run the VDF in order to farm, I count that as part of the farming requirement.
MMX needs a GPU to be able to plot - but not a super recent or high end one, I have one machine that’s done some plotting on a GTX 1070TI. Not like spacemesh taking a MONTH (give or take a day or two, LITERALLY) to do one plot with a RTX4070TI (and that plot was less than half the drive!).
I can run a node on a AMD 7 7700X that has a Vega 7 iGPU, which is plenty to verify VDF.
However, it is not required to have any iGPU or GPU, even for VDF. See this post > Discord
So, yes, it is entirely possible to run a node wo/any GPU (or iGPU)!
I made this same assumption, until I was corrected, and then tried it, setting OpenCL Platform/Device to None in the GUI settings to force VDF verification to the CPU, and it works fine w/ certain modern CPUs with SHA(-NI) extensions. There really should be a list of compatible ones somewhere.
Max never ceases to amaze 
I wish everyone success with MMX, I’m not going there, my farming days are over.
My server and it’s drives were clearly long over due a clean, I usually do this every so often, but clearly not often enough.
These are the bottoms of my 5 x 18TB USB drives, which were mounted on a couple of fans.
I still have two HDD in the server, as it does other duties, but may buy an NVME board and just mount drives on that - I don’t need the space I have now, an 18TB and a 16TB setup in Stable Bit Drive Pool.
Depends on if your CPU is new enough to support the SHA extensions. Rocket Lake (2021) or newer for Intel, Zen (2017) or newer for AMD, per Wikipaedia.
My farmer machine uses Ivy Lake generation CPUs, which aren’t new enough (2014).
So it’s possible to not need a GPU - but not automatic.
Pair of E5-2697 v2 were taking ballpark 30 seconds to verify a single VDF, which is WAY too long and was not working (needs to be under 10).
Machine prior to putting the GT1030 in it had a GPU, but an old Matrox design that does not support OpenCL at all.
Looks like I’ve pretty much halved my baseline electric usage from around 600w to about 300w. Not a huge saving, but it all adds up, and also not the main reason I stopped.
Hi Ronski:
I am sorry that you are leaving the farming, as an important member of Chia community and in this forum.
Questions apart regarding MMX (which I don’t know and would like to)
Regards from Mexico!
Thank you, you can learn about MMX on Max’s Discord channel.
Why not, I’ve just had enough, it may go somewhere, it likely won’t though, it’s just another crypto gamble.
I understand you; while I appreciate Max and his genius, I too am done with the crypto casino. Too much time, effort, and expense in chasing potential profit. Just let the S&P 500 do that work for you.
Exactly that. I’ve had to declare how much all my crypto was worth when I received it, and have to pay tax on it, even though it gone down in value.
If I put the money into my pension (instead of buying hardware to chase the crypto dream), the government gives me the tax back that I paid when I earned it, so straight away a 20% increase, then as the markets rise that does the work.
