A New DIY PC build or a New Dell Precision T3640 - Part 01

Both will be in brand new condition. Well, the DIY PC build will use the DDR4 3200 RAM modules that I have laying around. A comparable DIY PC build to the Precision would cost around $60 USD more to the Precision since I received a discount on the Precision. On the DIY PC build, I used the Corsair 100R to be fair with the Dell Precision T3640 as the Precision has a great computer case. Comparable DIY PC build. https://pcpartpicker.com/list/JC2G4d
