The one I had would frequently drop the drives, wreaking havoc on my (software) RAID5. I later found out that it was splitting 2 ports into 4 in a way that completely broke spec.

I don’t want to speak to your specific use case, as it’s outside of my wheelhouse. My main point was that SATA cards are a problem.
As for LSi SAS cards, there’s a lot of details that probably don’t (but could) matter to you. PCIe generation, connectors, lanes, etc. There are threads on various other homelab forums, truenas, unraid, etc. Some models (like the 9212-4i4e, meaning it has 4 internal and 4 external lanes) have native SATA ports that are convenient, but most will have a SAS connector or two. You’d need a matching (forward) breakout cable to connect to SATA. Note that there are several common connectors, with internal and external versions of each.
You can use the external connectors (e.g. SFF-8088) as long as you have a matching (e.g. SFF-8088 SAS-SATA) breakout cable, and are willing to route the cable accordingly. Internal connectors are simpler, but might be in lower supply.
If you just need a simple controller card to handle a few drives without major speed concerns, and it will not be the boot drive, here are the things you need to watch for:
- MUST be LSi, but it can be rebranded LSi. This includes certain cards from Dell and IBM, but not all.
- Must support Initiator Target (IT) mode. The alternative is Initiator RAID (IR) mode. This is nearly all, since most can be flashed to IT mode regardless
- Watch for counterfeits! There are a bunch of these out there. My best advice is to find IT recyclers on eBay. These cards are a dime a dozen in old, decommissioned servers. They’re eager to sell them to whomever wants them.
Also, make sure you can point a fan at it. They’re designed for rackmount server chassis, so desktop-style cases don’t usually have the airflow needed.
To anyone reading, do NOT get a PCIe SATA card. Everything on the market is absolute crap that will make your life miserable.
Instead, get a used PCIe SAS card, preferably based on LSi. These should run about $50, and you may (depending on the model) need a $20 cable to connect it to SATA devices.
I did this back in the days of Smoothwall, ~20 years ago. I used an old, dedicated PC, with 2 PCI NICs.
It was complicated, and took a long time to setup properly. It was loud and used a lot of power, and didn’t give me much beyond the standard $50 routers of the day (and is easily eclipsed by the standard $80 routers of today). But it ran reliably for a number of years without any interaction.
I also didn’t learn anything useful that I could ever apply to something else, so ended up just being a waste of time. 2/10, spend your time on something more useful.

I’m not saying you should avoid it (“Be greedy when others are fearful”), but you should really make sure you understand what you’re getting into.
It won’t officially work, but it’s not too hard to get it going. I just moved a similar box to 24H2 LTSC.
OP, you’ll probably need to run “setup.exe /product server”, or follow a recent guide. You’ll also need to do this for every major upgrade (i.e. yearly)
I agree though with the plan to use this as a test ground. I also recently upgraded a Lubuntu system to similar specs, and it runs pretty smoothly. But learning Linux takes a lot of time they don’t have.

Those of us who go the route of a NEMA 14-50 outlet are likely unaffected.
That said, I wish they’d ban the cheap, shitty outlets that can’t actually provide continuous power. These are the very popular $10 outlets, vs the $50 ones that also can’t fit in a standard box.
The big caveat is that the BIOS must allow it, and most released versions do not.

If you are of sound mind and body, not under the influence of drugs, extortion, etc, then the consent is valid.
Part of the problem is that everyone is at least a little deceitful, and these have been used in courts to claim rape. I remember a case about the use of makeup (deceiving about her actual looks and genetics), and another about being the “wrong” ethnicity. Where is the line for the courts to be involved?

Is it really that much less efficient? The only thing I can think of is the aerodynamics, but that’s a 40% difference.
Thinkpads are extremely well documented. For how to repair/replace parts, you need the HMM. Just Google for “Thinkpad t14 Gen 1 HMM” and you should find the official PDF on their site. That will tell you, step by step, how to replace the keyboard.
As for the part itself, you can again check Lenovo’s site for all compatible parts (FRUs) and find the item number and details. While I wouldn’t recommend buying directly from them due to cost, this should give you the information needed to find it elsewhere. eBay has tons of Thinkpads being sold for parts, and many of these will be parted out. You should have no issues finding what you’re looking for.

I don’t know how many are dealt with on Mastodon or Lemmy (or how you’d even get reliable numbers for that), but something tells me it’s a lot less than the bigger platforms these days.

Missing pins are actually extremely common. If your board has a slot that’s x16 (electrically x8), which is very common for a second video card, take a closer look. Half the pins in the slot aren’t connected. It has the full slot to make you feel better about it, and it provides some mounting stability, but it’s electrically the same as an x8 that’s open.

Or did you redefine O365 to only mean the web version?
Kind of. They will be multiples of 4. Let’s say you got a gigantic 8i8e card, albeit unlikely. That would (probably) have 2 internal and 2 external SAS connectors. Your standard breakout cables will split each one into 4 SATA cables (up to 16 SATA ports if you used all 4 SAS ports and breakout cables), each running at full (SAS) speed.
But what if you were running an enterprise file server with a hundred drives, as many of these once were? You can’t cram dozens of these cards into a server, there aren’t enough PCIe slots/lanes. Well, there are SAS expansion cards, which basically act as a splitter. They will share those 4 lanes, potentially creating a bottleneck. But this is where SAS and SATA speeds differ- these are SAS lanes, which are (probably) double what SATA can do. So with expanders, you could attach 8 SATA drives to every 4 SAS lanes and still run at full speed. And if you need capacity more than speed, expanders allow you to split those 4 lanes to 24 drives. These are typically built into the drive backplane/DAS.
As for the fan, just about anything will do. The chip/heatsink gets hot, but is limited to the ~75 watts provided by the PCIe bus. I just have an old 80 or 90mm fan pointing at it.
