Aurora R12, GPU and CPU help

Thank you for the reply, about the fan size mistake, pardon me as it must have been a typo, I do have an aurora r12, I added the product and must've removed it when revising, sorry. I will revise what I'm getting, sorry for the mistakes. If you have any recommendations, feel free to tell me.

No need to apologize for typos . . . everybody makes them. I was pretty sure I understood what you meant. It looks like you have a graphics card and CPU in mind, and an AIO cooler to complete your upgrade. What kind on recommendations are you looking for??? How big of a project do you want???

The Gigabyte graphics card you linked, at 286.5mm long, will not fit without minor mods. You would need to remove the lower front intake fan and bracket. You may be able to replace that fan with a Noctua 15mm fan. You mention a 15m fan, and then call out a 25mm fan by name.

The CPU you linked will work. The page you linked shows an i9-11900K. Again, this would work, but you should be able to find an i9-11900KF for less $$$. The R12 motherboard does not support CPU onboard graphics, and there is no graphics port in the rear I/O panel . . . so no sense in paying for a CPU that is onboard graphics capable. All of this assumes you have an Aurora R12.

An RTX 2080Ti Founders Edition graphics card would fit without modifications.

I honestly don't need anything big. Just a rig that can handle most of today's games, at a stable fps. I've spent so much time upgrading most things on my pc, and these are the last two things I need before I can settle down and enjoy what I had done. So, If there are any better options that match what I had in mind, please take the time to guide me to a better option if you don't mind.

I don't understand why you are choosing the RTX 2080Ti when you could get the RTX 3070 or 3070Ti for about the same price as the Gigabyte you linked. That would step you up to Ampere technology. I don't play video games, so I don't really know what difference that would make to you and your games. If there is some reason you particularly want the RTX 2080Ti . . . let me know so we can jump down the rabbit hole.

Yes you are correcy, a 3070 would be better. I think it was just bad research and a rushed decision on my end, after doing a little further investigation I have decided on the 3070. As it does has many more benifits than the RTX 2080 TI, I wont be getting the 3070 ti as I realize its bot worth the extra buck just to have it. If you want we can talk about the CPU's again and what you meant by "onboard graphics". Thankyou.

Good decision on the graphics card.

The difference between the i9-11900K and i9-11900KF is that the "K" processor has Intel UHD Graphics 750 . . . where the "KF" does not. The UHD Graphics is a CPU graphical interface that, when supported, you could connect your monitor to a graphics port in your rear I/O panel and view video without a graphics card. Your R12 does not support onboard graphics and has no such port in your rear I/O panel. Therefore, there is no reason to pay for a CPU with onboard graphics since you cannot use it in your R12.

Turns out I was actually looking for the Kf version, just found one that I thought was it and didn't notice that detail. But anyways Thanks! Never knew what that meant. Also, may you tell me how you get the sizes of the graphics cards I mentioned? Just wanted to know for future use.

For best information on graphics cards, or any other component, best to go to the manufacturers' web site Gigabyte  You didn't mention a specific RTX 3070, but if you can get a Founders Edition that would be a good choice, though not required.

Only one little inconvenience, I cant ever seem to find one available that doesn't have a insane high price, is it just high demand or can I not find one? Ps: I have a Noctua 15mm laying around I can use whenever.

Just look for a graphics card in you price range . . . try to stay under 270mm long, if possible.

Found a pretty good Asus Dual 3070 that looks nice, Here. 

Looks nice . . . measure from your motherboard out to the triangle brace in the PSU swingout contraption to make sure 5.31 inches wide will fit with the PSU closed.
