Yup. My old Corsair case weighs about 60 lbs. if not a bit more. It's all sheet metal and has space for 8 external fans plus some additional internal ones for the hard drives. I also paid a lot for the case 16 years ago. While it's no longer being used for my current PC, I'm not getting rid of it either even though it's getting a bit worn. Replacing the fans and the drive door latch is not difficult and it'll still be carried forward for another machine someday if I can ever afford to build machines on my own.Commercially you do not design cases, you build them. A good case weighs more than 40 pounds. My Cooler Master (old PC) weighs 45 pounds. 4 fans including power supply.
They never used to be this way. I went with Dell because my motherboard died when the parts prices were at their highest and they had what I thought at the time a decent system on sale. It helped that I had an account with them and a decent credit limit to afford a nice system. As always, I have the best of luck when it comes to stuff like this and my system had to die when the prices were at their peak, otherwise I would've built one myself.I've discovered Dell does not sell computers that can be upgraded. They want you to buy a whole new computer when the one you have wears out. Both my daughters had Dell computers. (Alienware) One had a power supply fail. I took a spare I had to fix it and found it wouldn't fit the case. Even the connectors wouldn't match up so I couldn't even just set it outside the case to get her computer back up and running. It was a standard size power supply and it wouldn't fit. Dell is notorious for their proprietary hardware. This is fine for office computers that are bought in bulk and replaced as a complete unit as needed but is not consumer friendly.
That's exactly why I did what I did to lower my temps. Given the cost of components these days, I didn't want to purchase another CPU or video card. The i9-12900K and newer run at about 100C max. Imagine pushing the CPU to its maximum temperature threshold. This is the same with the new NVidia video cards with their 83C limit. My RTX3080 was pushed close to the limit with the case side on which caused the thermal protection to kick in. This caused stuttering as the GPU would cool off just enough to drop below its maximum operating safe temperature and then go back up to 83C again a second or two later repeatedly.Large external fan on top of the perforated case.
TRS2022, with full graphics options, hits the CPU with 100C and it gets hot. TRS2019 temperatures stay in mid 80'sC with full graphics options. Room temperature 77F. People who do not monitor are possibly reducing the life of their CPU unknowingly. A free APP such as Core Temp can save them grief and hundreds of dollars.
