Well ASICs aren't as simple as you vision them. In case of GPUs, you get six of them and install a mining rig or even 2, 3 or four of them and put them around the house and still not feel them. I'm talking about noise and a noticeable increase in electricity bill.
But that's not the case for ASICs miner. They make a lot of noise, produce a lot of heat, need a lot of wattage. And of course they cost a couple thousand dollars. They need special treatment if you plan to install a few of them as you need to manage air circulation and stuff for cooling.
Noise is a real thing. You can't do what you do with a gpu rig and keep it in your bedroom.
They're smaller, and work out of the box with less maintenance.
Well nothing is simple as it seems. Everything has its own issues. I don't get what maintenance you're talking about. Once you get a gpu mining rig set up the right way with a stable hashrate, you're done. Like for a few months.
You'd literally have nothing to do with it except maybe selling the coins you mined.
Anyway, if you just wanna test it out go for it but I was trying to give you a small summary of what lies ahead.
