Reminder: The Dero Project team are getting ready to upgrade to our new Atlantis mainnet - testing is nearly complete and we will announce a block height snapshot soon

1. The devs did not announce yet which algorithm will be used for mining after Atlantis, so we do not know if GPU mining will be possible (or profitable) on Dero. Maybe it will be not Cryptonight-family at all, or only CPU mining with daemon will be possible.
2. For mining rig 4Gb ram and 64Gb SSD is enough. You don't need hdd 500gb at all.
3. Power supply unit 600w will be enough only for ~2 video cards AMD and for ~3 NVidia. You should sum energy consumption for all your video cards and add ~100-150 W for the processor and other stuff.
4. Note, that AMD Ryzen 7 1700 processor gives ~520 H/s with overclocking on CryptoNight-V7, the same as Nvidia GTX 1060 - 6 Gb. But it gives only ~200 H/s on CryptoNight-Heavy (GTX 1060 gives ~420 H/s on heavy).  I5 3570 processor has only 6Mb L3 cash memory, so on CryptoNight-V7 you can use 3 threads with ~70*3=210 h/s and only 1 thread on CryptoNight-Heavy with ~70h/s, as it requires 4Mb L3 cash per thread.
5. AMD Ryzen 7 1700 is more energy effective with the same hashrate than Ryzen 7 1700x or Ryzen 7 1800. For Ryzen I suggest to buy a good cooler, as the cheap one will be noisy on full load. AMD processors are hotter than Intel.
6. RX560 4Gb is not good either, as it gives only ~310 H/s. The benchmarks for CryptoNight-V7 you can find here: https://docs.google.com/spreadsheets/d/18IrFEhWP89oG_BTUsQGS5IDG8LUYjCHDiRQkOuQ4a9A/edit#gid=1518673099

Yes, it will be anti ASIC.

CryptoNote is the protocol. CryptoNight, the algorithm, isn't anymore. But there are lots of ASIC resistant variations of it so far.

You need to have some knowledge of "computer stuff" to mine crypto; no way around it, I'm afraid.

At least in the very beginning DERO Atlantis will only be mineable with a CPU using the official wallet daemon. I wrote a post a couple pages back that people have been brazenly plagiarizing on how to mine with the daemon in Windows so go read that... several times if you have to. It's really not that difficult.

Unknown, but seems likely since the POW algo had to change to achieve the transaction speeds our wily ol' Cap'n is claiming. That said, I imagine it is tough to give up the apparent affirmation of >1GH/s on your network, but it really would be for the best long term. I am ready to switch my pokey little 4x RX 560 rig back to DERO as soon as the ASICs get booted off, but right now it would be supremely stupid for me to attempt to mine it (I wouldn't even earn 1 DERO per month...).
