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.
