Apple Mac mini 2.8GHz Dual-Core
In terms of raw performance, this model is one of the best nettops out there. While there are a few different models offered by Apple, the 2.8GHz model offers the best overall components. It has a dual-core processor featuring an Intel i5 chip, but you can upgrade to an i7 3.0GHz processor if you want faster performance. It also happens to have a 1TB hard drive and 8GB of RAM which can be upgraded to 2TB of storage and 16GB of memory if you really need more power, though that will also raise the cost of this pick quite a bit more.
has an Intel graphics chip, but no dedicated video memory, which is an unfortunate weakness with this model. You get both Wireless-AC and Bluetooth 4.0 connectivity, along with four USB 3.0 ports and two Thunderbolt 2.0 ports. This model has an Ethernet port and HDMI connection so you can use it with a wide range of networks and devices.
