Hi, I am looking at a used iMac online and was wondering if any of you could please help me decide if it's a good deal or not. This is what the seller has to say: $1,050 Wow! Do I have a deal for you today. This Rentia 4K iMac, 21.5 inch, late 2015 model will go fast! DONT OVERSPEND IN THE STORE, BUY HERE! If you need a great home computer for you or a student, this is the one. I’ve decided to take the dip in building computers again and I will no longer need this beautiful Apple product. It’s almost brand new I’ve used it so little. It must have under 40 hours of use right out of the box! Specs are listed in the photos above. Contact for more information. I will need this iMac gone by May as that is when most of my parts will be arriving. Here's a pic of the specs they have in their post: I currently use a 2009 MacBook Pro running El Capitan that, while it still works nice, is old. I can't update it any further and it has been lagging lately when I edit large photos in Photoshop. Here are the specs on my laptop: Version 10.11.6 (15G1010) MacBook Pro (15-inch, Mid 2009) 2.8 GHz Intel Core 2 Duo 8 GB 1067 MHz DDR3 NVIDIA GeForce 9400M 256 MB I have a 1 TB SATA Disk hardrive installed on here. Not sure what the seller has on the iMac. Since my laptop is a refurb with some better parts thrown in do you think this iMac would be an upgrade and worth the $1,050? Thanks in advance.
