Dell builds obsolescence into every model it sells. Cheap power supplies and loaded memory slots are just the beginning. I wish i had a dime for every Dell user who wanted to upgrade to a “gaming video card” and found out they needed a new power supply.
Luckily parts are cheap these days.
Another good reason to avoid them. Really Dell is just all around annoying. Which is probably why all the Mac people love to compare their products with Dell, I’m a died in the wool PC guy but if Dell became my only PC choice I’d either walk away from computers entirely or go Mac.
