Horrible build quality.  The built-in WiFi went out after less than an hour, now it connects but won't stay connected more than 7 seconds at a time.  The slot covers on the back of the case weren't punched completely, they were still partially connected to the rear of the chassis.  Rhe are supposed to be held in place by a flip cover that has retaining screws, but the screws were missing and the cover was stuck and wouldn't rotate to give access anyway.  I had to pry it open to remove the slot covers, which had to be punched out - see above - just to install a video card.  Which, BTW, is the only card that can be installed because it is the only slot that lines up with the case openings, because the motherboard doesn't match the case design.  15 years ago Acer made decent value-line laptops.  Based on this unit, and some comments I've read from those with similar experiences, I can't recommend Acer for anyone.  You might luck up and get one that works, but you are equally likely to just get trash.Update:  The slot covers aren't.  They are just punch-outs, there aren't any true slot covers.  So, if you remove one to install a card, then remove the card, there is nothing to put back to cover that slot.
