"Functional and supported for a long time"
They will only support during warranty (I assume) and will not renew warranty if you have a problem.
I have an a200 that I bought refurbished in June 2022, and it lasted for 15 months before a major failure (boot disk showing bad sectors). I basically solved it by reducing space usage to 1/2 disk space, cloned the failing SSD and was ready to install a brand new one myself. But then a month later something happened with the GPU, power supply, or mainboard, I'm not sure which. The GPU basically doesn't output video, so the only way I can access the system is to log in through remote desktop from another computer.
I've been in touch with Corsair support and they are basically worthless. I'm so glad I didn't pay full price for that garbage, which was discounted $1000 but still $2000 too much for what I got. The Corsair One Pro A200 is by far the most unstable, shortest lasting premade system I've owned, which includes a 1998 Dell Precision workstation (12+ years), HP laptop 2003 (8+ years), Sager Laptop (10+ years and still usable), Lenovo Yoga X1 (6 years and still in regular use).
