It's amazing just how bad this is. Just what I quickly found to be wrong reading though it:
Pippy and Dolphin -
1: Puppy and Dolphin do mix and match. There's nothing stopping you from using a 2600x in an X470 or a 2700x in a b450.
2: 8gb of RAM for Puppy and Dolphin? 16gb is really the minimum, especially when you aren't even getting good RAM.
3: A 1060 for Puppy and Dolphin? A 580 or 1660/1660 super is just better and/or cheaper
4: No SSD? In 2020? I hope you're joking.
Narwhal -
1: The Phanteks P400A is currently cheaper and way better than the H510
2: On the subject of cases, the H510 doesn't support an internal DVD drive
3: A 9600k? No. The 3600 is just better in every way while being cheaper.
4: PSU is bad. Not "blow up" bad, but overpriced for what you get. You can get a fully modular Corsair RM650x or SeaSonic Focus+ Gold 650W for around the same and they're just better.
5: You could at least link to one of the 2060's that cost 300 instead of 360 dollars.. There's no point getting the 360 ones at all.
6: Samsung is just so overly expensive it's kinda pointless
Unicorn:
1: The Phanteks P400A is currently cheaper and way better than the Define R6.. So much cheaper and so much better. Though you lose out on the DvD drive, but that didn't stop you in Narwhal..
2: A 9600k? No. The 3600 is just better in every way while being cheaper. Again.
3: Again, link to a 300 dollar 2060, or maybe a 2060 super. The 2070 is awful, and you shouldn't buy one. Hell, if you really want 2070 performance, get a 5700xt for cheaper.
4: Samsung PRO drive? HOLY FUCK NO. Not only are you paying the Samsung tax, you're paying the pro tax on top of it. It's LITERALLY 2 and a half times more expensive than the MX500. Do not buy the Samsung pro drives.
