Since a laptop thread got me thinking about it, I’m posting a quick desktop build to demonstrate how inexpensively you can run CAD on a desktop PC.
Ryzen 3 3200G processor ($95)
8 GB (2x4GB) G.Skill Ripjaws V DDR2400 Memory ($44)
Crucial 500 GB M.2 SSD ($70)
MSI PRO B450M Micro ATX Motherboard ($75)
Rosewill Micro ATX case ($41)
Thermaltake Smart 430W power supply ($38)
That’s a $363 desktop box that runs Inventor very nicely. The one I run at home is really similar to that build. I’ve thrown a lot of decent sized robot models at it, and it handles them very well. The Vega 8 graphics with the Ryzen cards get the job done. I really like Ryzen 3 at its price point when its integrated graphics (better than Intel’s) are taken into account.
