> That said I do like the new sealed CPU cooler systems - AO I believe they call them where you get the radiator and CPU block already sealed and the pump is in the cpu block.

Yeah, I bought a water cooling version of this for the gaming rig i built way back when. It was much cheaper (and less scary) than building a bespoke water cooling system 😂 All i had to do was fit the water cooling radiator/reservoir inbetween two fans sucking air from outside the tower, and then attached a connected cooling unit to the cpu. It was all ready built, pipes attached to radiator/reservoir and to the cpu unit. 

I wanted to play assassins creed vallhalla when it came out, but my gpu didn't have enough vram. Strangely, cyberpunk 2077 works on my rig, but only at mid graphic settings. Red dead redemption works at mid/high... but overall it runs well for a pc built in 2011. All I've ever upgraded in it since the build is upping my ram to from 8gb to 16gb and i bought a new gpu about 5 years ago. But cause i sold my old one on ebay, the new gpu only ended up costing about £70 if memory serves me right.

I have to admit that my computer building days are probably past me tbh. But it's good to have the knowledge and confidence to take my current system apart to do a deep clean, which i do at least every few years. I'm guessing that's why it's lasted so well.
