Hi All,
After receiving a-lot of great advice the below is what I have built. I will post photos once I have put the new desk together.
In the end I decided to replace the old power supply and grabbed a new case so the cost went up a little. I am sure I could have made some better choices but prices are insane at the moment so I tried to focus on upgradeability so hopefully this lasts me a few years at least.
CPU: i5 12600k
Cooler: NH-D15s with a single fan
Memory: Kingston FURY Renegade 32GB (2x16GB) DDR4 3600MHz CL16
Motherboard: MSI Z690-a PRO WiFi ( I have needed WiFi a few times in the past so thought it would be nice to have)
PSU: Corsair Rm750x
SSD: Samsung 970 Evo Plus 1TB
Case: Lian Li Meshcool 2
I haven't installed windows just yet, I have updated the bios and will hopefully do the rest tonight.
Some notes from this build: My last build was an i5 3570k so I am a bit rusty.
The case was a dream to build in, so much space and cable management was super easy, I can imagine it would be a-lot easier if the PSU cables were not so stiff and the braiding was tighter. I draped the cables over a warm heater for 5 min and that made them easier to bend into shape. One thing to note about this case is if you want to remove the HDD cage you need to do this before installing your PSU.
The NH-D15 is a monster, I have never seen one in real life so it surprised me. This is the only part of the build I am not 100% happy with, the mobo is so tidy with good cable management and the ssd hidden under a heat sink then BAM an enormous ugly cooler, should have gone water but a part of me wanted to try higher end air cooling.
I am running the stock fans at the moment but will change them soon and add a rear exhaust.
I will update this post as I finish off the build!
