No problem. If the S9 option is appealing to you, I'll elaborate a bit more on it.

There are a few vendors where you can get a S9 like Kaboom racks, D-central, Zeus mining etc. Some vendors will sell them without a PSU so make sure that if they offer that option, you get one with a PSU or you won't be able to power your miner.

You'll want to swap out the fans to make this miner quite if using for a space heater. The stock fans are quite loud. The Arctic A14 and Noctua NF-14 are both good options with a slight edge to the Noctua fan, which you will have to pay a little more to get. These will require a 3D printed adapter to fit onto the S9 as they are 140mm fans, the miner is meant for 120mm. You can download the files to print yourself or buy them from places like Crypto Cloaks or D-central.

BraiinsOS/Pool is an easy way to get started, you can flash BraiinsOS to a SD card and create a Braiins account to point your hash at their pool. If you want to connect your miner via wifi, get a Vonnets device (https://a.co/d/gpah0ii) otherwise you can connect directly into your router via ethernet.

Like I mentioned in my post, Crypto Cloaks has a case that you can put your S9 in to make it more aesthetically pleasing. If you don't mind the miner looking like it does, the case isn't necessary.

I just did a little diagnosis and configuration on a S9 space heater that someone I met on nostr asked me to work on. Just sent it back today to a happy pleb!

A bitaxe is a cheap way to get introduced to home mining.

It uses about the same amount of power as a phone charger and basically gives you a lottery ticket every ~10 minutes which is the main use case here. I don't think its worth it to contribute your hash to a FPPS (Full Pay Per Share, aka a steady stream of guaranteed payments based on the hashrate you contribute) pool.

If you want to earn some sats to off set utility bills by using a miner as a space heater, I would recommend getting an Antiminer S9. Crypto Cloaks sells a case for these to make it a bit more aesthetically pleasing and BTC sessions has a tutorial video (https://www.youtube.com/watch?v=csmHvuzUECU) on how to set it up. While the efficiency on the S9s aren't the best, it is the most budget and user friendly way to get into home mining while earning a steady stream of sats via FPPS pool like Braiins.

If you really want to tinker, look into the Loki kit by Pivotal Pleb (https://pivotalpleb.com/). Their kit allows you to run a S19 hashboard from a normal 120V home outlet (they normally use a 220V to 240V). This does require some modification of the PSU (Power Supply Unit) but some resellers like Altairtech.io sell them already modified so that they are plug and play (Theirs is called the Ulacher https://altairtech.io/product/urlacher/). This option is a bit pricey, but the miner is much more efficient than the S9.
