Even if you're a geek who's steadfastly refused to consider all-in-one computers, Lenovo's new Ideacentre AIO 700 might be worth a look. It sports a 24-inch or 27-inch display in up to a 4K resolution with multitouch, but most importantly it comes with a dedicated graphics card and it can also be easily opened up. That means it'll actually be able to play some decent games, and you have room for upgrades down the line (which is pretty rare for all-in-one PCs). The AIO 700 can be configured with either an Intel or AMD CPU, and you can also add in an Intel RealSense camera (which will also speed up your Windows 10 logins). We only confronted it briefly at a press event yesterday, but we were struck by its sheer immensity. The 24-inch AIO 700 starts at $1,099 while the 27-inch model starts at $1,899. Both will ship in October.
