Hi All, I am wanting to buy a used Mac Mini and need some advice from people who own these devices to which model you suggest is best to purchase. My budget is $450. I have been looking at buying from Powermax. Has anyone purchased from them before? I did a search for mac mini and found these models: https://www.powermax.com/productcategory/used-macs-intel-mac-mini The price looks pretty good and they appear to have really good feedback. I want to use the mac mini for video editing and dont want any lag during editing and playback. Any advice would be great!
