I see lots of mobos with those little hard drives on a stick. I think they called NVME or something, may have spelling wrong. For most people, that is likely awesome. For me, I think I'd be happy with a regular SSD. Given that, I'd like them to make a mobo where one can say cut off/disable that NVME thing and make use of that "lane" as a PCIe slot(s). Even if that means having a cable that hooks to the mobo and runs elsewhere to connect PCIe cards. In other words, have one slot that is expandable to say three or four slots with what I think is called a back-plane. That way if a user wants to use the NVME thing, they can. If they don't, they can disable it and go another route with PCIe expansion. Sort of reminds me of that SAS drive thing. You have one cable that branches out into several SATA drives or SAS drives themselves. I don't know a lot about SAS really. May have to read up on that with that new case that holds 18 drives tho. O_o I have considered getting a server type mobo and CPU for my new build. As you point out, they are packed with features I could likely use. Thing is, the price tag makes me faint and fall out of my chair. Even used ones that are a couple years old, in the floor I go. -_- I looked up a SP5 AMD CPU, pushing $800 just for the CPU on Ebay, used. The mobo isn't cheap either. I don't know if that would even serve my purpose. I may need something newer and even more expensive. I'd have to be able to put it in a regular case tho. No room for rack mount stuff. The biggest thing I need PCIe slots for, drive controllers. I thought about buying a SAS card and having it branch out into a LOT of drives. Still, I might need two cards even then. It's like looking at the cereal isle in a store. All those choices and most of them . . . . are corn. ROFL Dale :-) :-) P. S. To all: There was a news item recently about grub updates and reinstalling to the hard drive when updating. I just synced and there is a new grub update. Make sure to see if grub updates for you and if so, don't forget to reinstall to the hard drive. For old BIOS users, usually a grub-install /dev/sda will do. You EFI folks, you on your own. Gentoo wiki has the command. I've never had EFI stuff, yet. Hope this heads up helps someone.
