I swear, with most of the ‘wen lambo’ posts, it ends up being this. I gotta learn to keep walking.
Please share and instruct me how to Farm or Plotting. Many thanks
Hows your look up times on the Cassette tapes?

Great !!! Thanks a lot
yes letmegooglethat is arguably the best website in the world
What started as Fun project turned into high-efficiency plotting farming. Key to success is efficiency - max. density per W in server, and max plots/day/watt.
Multipurpose workstation:
- AMD Ryzen 9 3950X PBO hitting 4.2GHz on all 16 cores, cooled by Corsair H150i AIO.
- Ripjaw 128GB clocked to 3600MHz 18-20-20-20-40 with extra fan for cooling (after 20 years, they still didn’t learn to cool RAM modules :o)
- tmp Corsair MP600 2TB (still cheap king of hardcore plotting)
- ASUS ArtPro B550 (used to run ASUS Crosshair Hero VIII Wifi X570) mobos
Current tuning by HR IT does <20min/plot @ 150W or 50W plot. Each plot costs 0.05 CHF.
Farming 5RO rack server/rig:
- Old used SuperMicro X10 MB with some Xeon CPU and 32GB RAM purchased for 200CHF
- 2x IBM M1015 flashed to LSI 2008 + 2 x Intel RES2CV expanders
- 40x HDDs fed by single 1000W Seasonic high-efficiency PSU
About 600TB and ~260W. Currently expanding another 8 x HDD with 140TB, which will screw up efficiency little bit thanks to hooking up second PSU.
At current prices there is no difference between expanding HDDs in server or just buying XCH.
Currently working on new version of HDD trays with improved cooling, reduced place. Revisiting 12/5V voltage regulator to feed this beast just with single PSU for max. efficiency.
We will see, server can run 120 HDDs (so far only theoretically)
I may add some more HDDs, but there is again upgrade costs that I want to avoid.
One year later and 30 TB HDDs may be better upgrade for max. efficiency, than expanding quantity. 10 or 20 TB, HDD still have 6-7W. Efficiency is the key.

Below 0.5W per TB is impressive

Unless, you have free energy…you work on efficiency 
We got a present +44% energy price hike from 2023 (despite we have two hydro energy projects in backyard, but we must share pain with lowlanders and concrete jungle monkeys )

First baby Jbod is getting ready to take it’s first steps 
12 disks, 2U and only 40cm depth (which is a good thing because my rack is only 50cm). Power and SAS connection directly from the main farmer.
P.S. gods, stainless steel is hard to drill through 
With the parts I’m selling from the old servers, these should be around 40,- euro all-in when done.

you just need proper tools
Don’t use wood/paper steel HSS drills commonly sold in hobby stores. Aim for stainless steel optimized HSS drill with coating…it costs like 5$/drill…you can drill with your 3rd arm 
I doubt it is inox though…it would cost a fortune…they used galvanized/zinc-coating-like if I recall…such as automotive. It makes the first few microns of surface very hard/corrossion resistant…until you drill through

yeah it’s not inox but something steel + corrosion resistant stuff.
I’m getting a 6pc set of 5% cobalt drill bits today, that should do the trick I think

get something like this…we used it at work, where carbide is too expensive or risky to use.
Any high quality HSS-E (High Speed Steel Cobalt) TiN or TiAlN coating drill will do. Even uncotaed HSS-E is enough. I used them in car repairs with small Hilti powerdrill without issues…and you can resharpen them with hand at any time.
You can drill with accu power-drill or old-school powerdrill…it is like drilling butter.
Blue ring drills are optimized for SS steels…of course, with hand drilling is wear higher…unless, you have hands like Terminator
YOU BETTER SEAL THOSE HOLES AFTERWARDS BECAUSE IT WILL MOST LIKELY RUST…ONCE YOU DRILL OUT coating/galvanized surface.

Thanks for the tip, but I’m getting the ones from the local DIY store, want to finish today, so I can clean up the mess before the week starts haha

Am I seeing this right? Did you cut that server in half??
haha, yes I did.
To clarify myself: I have my farm standing pretty much in my living room. it’s a small 19"audio rack with only 50cm of depth, so most server cases / jbods don’t fit, besides I can’t have any of that truly insane noise that comes off those 60mm fans.
So yes I basically just cut off the drive bay section, replaced the fans with 80mm and now waiting for the parts to arrive so I can finish the power adapter to eps12v
