A:AnswerThis desktop's RAM is pgradeable to 32 GB DDR4-2666 SDRAM. I would recommend reaching out to a blue shirt member in the computer department to help you find the best RAM for your needs.
A:AnswerThanks for reaching out. This model comes preconfigured with the RX 580 which is an amazing GPU that can handle 4K video streaming and 1080p AAA gaming. You can certainly change out the GPU at a later date, you may also need to upgrade the PSU as well. I highly recommend trying out the RX 580 in this computer. You may find it will work excellently for all you are using it for.
A:AnswerThe RX580 supports 4 monitors. If you are having an issue I recommend reaching out to HP support or the Best Buy Geek Squad for troubleshooting.
A:AnswerYou should not have an issue running dual 1080p monitors on the RX 580. I recommend reaching out to Best Buy Geek Squad or HP support to assist with this.
A:AnswerI don't think there is enough room to install the radiator. There is only a single 80mm case fan, so even if it took that spot the rad would be too large. You would have to cut a hole in the side of you case to mount and vent an AIO radiator. Short answer - No.
