I’ve not been able to find a single Inventec B400 anywhere. Are these not sold anymore, not even as used on ebay?
The B400 was an ODM board, manufactured for a smaller server manufacturer. I tripped over it by accident, when I was looking for a suitable chassis for my build. I still get messages about it, which is amazing, despite posting about the build years ago
It was about EOL when I got mine, plus I think by comparison, there probably weren't a bazillion of them manufactured either. Anyone that was lucky enough to have scooped one up at the time, probably still has it running in a cupboard somewhere, they are robust.
I haven't seen any for sale in a long time, but I would be willing to bet there are still some old server chassis out there in the disposal market with one tucked inside. The closest board that is readily obtainable from that era, would likely be the x9SCxxx boards from Supermicro. Again, a really old board series, but can be had really cheap and is still plenty usable. For something a smidge better, you could also look at an X10SRI-F, throw in some RAM and a E5-16xx CPU etc. These are a bit more expensive, and will idle higher, but opens the door to more cores, RAM options, PCIe 3.0, more slots and etc
The funny thing about choice, sometimes there's too much of it, and you just have to roll the dice and move forward
