There seem to be a lot of negative comments about pre-built gaming desktops. I would like to disagree and make a suggestion for folks to consider. I just finished setting up my new off-the-shelf desktop that I purchased from NewEgg. It is currently on sale for $1199 with free shipping. I am EXTREMELY happy with it. 
MSI Aegis RS
i7-13700F
32 GB DDR5 RAM
RTX 4060
NVM 2 TB SSD
Win 11 Home
Included a wired keyboard and wired gaming mouse.
Trainz + is installed on the main C: drive. The data is on a USB 2TB HDD. It runs at 60 fps at the highest settings. The difference between my old (dinosaur) computer and this one is like going from a 2 cylinder moped to a Ferrari. After an initial slow load, the program opens almost instantaneously. It downloads from the DLS in the blink of an eye. I am not sure I care for Windows 11 Home, but getting used to Win 8 and 10 took a while. The only trouble I had was figuring out how to turn off the LEDS on the case and keyboard. They were driving me crazy. The biggest issue now is reinstalling all my other programs. It's not hard, just time-intensive.

 Mine has Corsair equipment for cooling, and the intake fans mounted at the “front” end of the case, with the GPU sitting horizontally in the middle. The CPU water cooler is mounted just above with the exhaust fans blowing out the top grill. There is another fan blowing out the top back, for the motherboard and CPU I believe (they are placed in the top back corner). The GPU‘s fans face downward and intake air from the bottom of the case, over the power supply. The setup never gave my cousin any problems, and Trainz has only maxed out the GPU temp at 74C. I use iCUE to manage the fans, and set them to the Extreme preset. In Afterburner, I leave the control to automatic. I feel the temperature of the exhaust every so often to gauge the temperature, and so far I’ve never felt really hot air, only warm.
