- I got the Dell M4800 15.6in FHD Ultrapowerful Mobile Workstation Business Laptop Computer, Intel Core i7-490 for CAD purposes and it works for the most part.- Has back lighting on the keyboard.- Works with Fusion 360 and Solidworks for the most part.- Came on time and was well packaged.- Can upgrade the storage space-The computer has some heft to it, the heaviest laptop I've ever owned.- It's refurbished so it had some knicks and scratches on it.- Becomes really slow when making detailed/ large CAD models- Battery life it low so it basically lives on the charger.
