I have 2 systems I'm trying to replace. For one of them, the motherboard has been unavailable for most of 2022. The manufacturer recently switched ethernet MACs, so I'm expecting it to start reappearing in the channel.
The other was blocked on unavailability of ECC DDR5 UDIMMs, for virtually all of 2022. Now, the price of the CPU and motherboard have gone up, which I was planning to use. I'll probably still buy the same spec, but maybe I'll at least wait a couple months.
I definitely plan on upgrading before the next geopolitical shoe drops. I was lucky that I didn't need to buy any hardware during the pandemic. I think I'd better not waste the opportunity to avoid getting trapped by the next supply crunch.
