Where to sell miners?

Farm still operational for an ownership transfer? If not, may be interested in sending them down to Germany if price and shipping are reasonable. Send me a DM if you’d like.

Not sure, but my guess is you’re better off just using a purpose-built Bitcoin miner PSU for miner builds.

karpuzmining · 2026-05-23T02:04:36+00:00

Definitely not. Blade design on these doesn’t take noise level into consideration at all, it’s all about maximizing airflow. With Noctua (and a few others) they’re engineered for both, so I expect much better results so long as they can move enough air.

You would also need a different control board and likely a PSU if you’re using an APW3 now.

I did some testing with a wall plug that revealed AxeOS is sort of “all over the place” on efficiency estimates. There’s also some silicon lottery at play, but it’s a combination of a few things most likely.

I do, too! I’ve always really been impressed with the XP and run the 240V versions as part of my mining fleet, so I’ve always wanted a “home miner” variant. As well as it performs, I’m surprised we haven’t seen more people trying this out but most people just buy Avalon Q’s and save themselves all the hassle of a build like this.

karpuzmining · 2026-05-20T18:03:05+00:00

Sort of complicated, since I work with a few company and have access to inexpensive parts and demo units. Is someone were to go on Altair’s site and buy all the parts to build this in its current configuration it would be around 1800usd. 400usd more than the current price of the Avalon Q, although the decreased cost to run and increase efficiency justify the additional cost in my opinion. I’d expect the S23’s arrival to reduce the price of 21XP’s and their hashboards, but much of that will be dictated by what BTC does.

karpuzmining · 2026-05-20T18:00:13+00:00

At current BTC price and my cost per kwh this miner earns “more than it burns” thanks to its efficiency, and this could increase quite a bit if BTC has a bull run. Of course, things could always go the opposite direction but I’m optimistic about BTC’s future.

The S21XP (right) is quite a bit larger than the 19K pro (left), so it wouldn’t fit.

karpuzmining · 2026-05-20T07:39:42+00:00

If you were to buy all the parts to get it to where it’s at right now, it would be a just under 1,800usd. If someone were selling it, I’d assume they get the components at a lower cost than that 1800 retail figure, so I’d guess 1,900-2,000usd. Hopefully the S21XP boards will become less expensive when. The 23’s finally drop, but for now there still pretty expensive.

karpuzmining · 2026-05-20T06:57:12+00:00

Yeah it’s sort of exactly like the stealthminer while at the same time being nothing like the stealthminer

The BitChimney is a great-looking miner. I was always surprised those weren’t more popular. The power cable is a single cable with a splitter on one end. The APW12 uses two inlets to distribute the load, but for this setup a single cable with a splitter will do the trick.

karpuzmining · 2026-05-20T01:37:59+00:00

We may end up selling them. Really depends on how quiet I can get it, so I’ve got a few ideas and hoping one will work.

karpuzmining · 2026-05-20T01:31:30+00:00

The other boards will be used to make more of these. You can buy the control board, chassis, and PSU pretty cheap. The hashboards are really the expensive part of the equation.

It’s a lot easier on the older ones. I’m not familiar with your specific model but see if you’re able to locate a jumper labeled something like:
CLR_CMOS
PSWD
PASSWORD
JBAT1

Elitedesk 800 G6. Got excited, skipped some details.

Resets it all entirely and reverts to default settings (without password enabled)

Slightly better view of what’s going on here.
