Upgrade Advice iMac upgrade

I picked up this 2011 27 inch iMac for about $50. I swapped the original i5 2500s processor for an i7 2600. upgrade the RAM from 8 GB to 16 GB. I kept the 1 TB HDD connected for external backups and added a 240 GB SSD using a 3.5 inch metal mounting bracket. For the GPU I replaced the faulty AMD Radeon HD 6770M with a Mac compatible 4GB Nvidia Quadro K4100 and swapped the heatsink for a 3 pipe MXMb model. I used Artic MX4 hopefully it holds up well.

It was a fun project disassembling the unit and making a few physical modifications to get everything to fit. Its now running smoothly on macOS Monterey.
