That’s silly. A motherboard with a free pci slot (I think x8? Been awhile), a cheap hba with the associated sas cables, and literally any case that will hold the drives. You could strap them all to a board if you wanted
Obviously you’ll need cpu and ram. Make sure the power supply is beefy enough to cover the amount of drives you plan to use and preferably get a good quality one if you plan to run it 24/7. I do think it’s worthwhile to get server grade hardware as it holds up better to long term 24/7 use but it’s not necessary. It’s also absolutely fine to go entirely used; my whole build was all ewaste and was maybe $300 minus the drives (which added much more). And my build was frankly overkill for a nas but I also run VMs and do some local llm stuff. If you just want to serve files for like Jellyfin/plex you really don’t need much, an ewaste pc from like 2015 will probably do the job spec wise (though increasing ram a lot can help significantly especially if you do zfs)
I have a 15 drive nas. My drives are sata but my hba is compatible with sas drives. I use an lsi 9300-16i and I have read of people using it with sas arrays just fine. If you shop around you can get it with cables for like $40-50 used (maybe more now since inflation fucked everything and you need the less common cables). Be careful because there are lots of counterfeits.
Also be mindful of cooling, the card runs HOT. I added active cooling to mine with a 3d printed bracket. If you’re only running 3-4 drives you could also get the 9300-8i which is cheaper and runs cooler, but has half the drive lanes so you’re limited in terms of future expansion.
preface: conjecture
musk and zuckerberg benefit from “othering” a group so that the majority of people get caught up in arguing about the rights of that group. While you’re busy being distracted by that they can push for agendas that benefit their companies and personal wealth, which inherently fuck you over.
musk does seem to have a personal vendetta as well given his issues with his trans daughter but I truly think this is ancillary to enriching his wealth and power. He also seems to love getting involved in topics that rile people up because deep down he’s a 14 year old reddit troll
rowling is double down and attention. She has a shit take, posts about it, people call her out. She’s a literal billionaire “beloved author” used to being surrounded by hangers on so being challenged wrecks her shit. Rather than reflect and look at scientific consensus she doubles down on her shit take. Because of people like above this gets her increasing amounts of attention and relevance so her beliefs are reaffirmed and deepened constantly. Now she’s consulted to speak authoritatively on the matter despite having no actual qualification other than being a rich lady who got into twitter arguments about it
Many of these apply to nobodies as well. Your stupid anti trans neighbor benefits from “othering” someone because it gives them someone to deflect blame onto. For most of American history it was black people, or Hispanic people, sometimes Jews, basically any minority. They also will double down when called out on shit takes and will absolutely respond to attention given for shit takes.
