In summary, at the end of the day here's a system that's a minimum of $1800 CAD (I'm in Alberta) above a similar, faster, much quieter DIY build. Yet, you get subpar B760 chipset, no 5th gen SSD, under utilized 14900k (only 200watts), no iCUE support for Corsair's own peripherals, super loud fans under load, totally inadequate cooling, and only available with the same wood panelling as my Mom's 1970s station wagon (although I personally like the dark wood look). You used to live with the limitations because the case was compact and you could travel with it if you wanted to, but this case is almost twice the size of an i300 (which I bought and promptly returned after finding all the same shortcomings as this new unit has). I think Corsair has lost their way here... I've had a crush on the their small form factor for a really long time, and I almost bought this on the spot despite the insane price because they finally had the load I wanted... thankfully, I stopped before pressing the confirm order button and took time to watch the reviews.

Correcting some errors I made in post above (which I can't delete for some reason?) CPU is cooled badly with a subpar "120mm" radiator/fan AIO in an intake configuration on side of case. Question - Since there are dual 120mm fans on the side panel, couldn't they have used a 240mm radiator for CPU? GPU is cooled reasonably well by dual 120mm fans/240mm radiator AIO that expels air out the top Note: GPU VRMs are not cooled at all. Not even a basic heat sync on them. They apparently run very hot but no one has reported heat related issues with GPU that I have seen Motherboard is MSI B760M - Works great, but no support for 5th gen SSD, while the Z790 chipset has 5th gen support. Wonder why they went B760 chipset?

I've watched a few reviews on the i500 4090 model and there seem to be some challenges. Fan Noise - Big issue (just like the i300) Extremely loud under load. Fans throughout are half height, moving far less air then a typical fan, contributing to heat issues below. Reviewer that replaced fans with standard height Corsair fans got significant heat reduction.... so why doesn't Corsair just do that? Heat - Same under par 170mm CPU AIO kit that couldn't cool the i9 13th, and definitely not the i9 14th. Reviewers putting CPU at 90c under load, sometimes hitting 100c CPU has been wattage (performance) throttled (just like i300) and still runs insanely hot GPU - Cooled by dual 140mm fans/radiator on top. Runs 50 - 60c under load, good performance numbers Case - Great looking but much larger than i300, but why, if they were not going to fix the heat, fan noise and CPU cooling/performance issues? iCUE - Apparently and inexplicably, no iCUE support in case you use Corsair peripherals as well and would like it I'd really like to speak to a Corsair engineer one day and ask them why they makes some of the choices they do.

Meh... just returned it to Amazon and got another one.

Also tried to reset the CMOS. It tried to start, then shut off, then tried again and just sat there... same situation... solid green LED front, fan starts and then stops.

I was using iCUE to upgrade the firmware on my Corsair K63 Keyboard. It asked me to install the wireless dongle which I did, and then unplug the usb cable so it switched to wireless. When I did that, the firmware update began. However, at the end it said firmware update failed. There was also an update for the CPU Pump (I think.. possibly the GPU pump) but clicking that update just said failed, over and over. So I restarted the Corsair One i300 which is just 3 days old now, and it didn't post. Just solid green light on the front LEDs and no post. Fan doesn't start. Just sits there. I popped the lid to see if the fan cable was connected and it was, but stopped there. Anyone have any idea how to breathe life back into my new system?
