MSI Nightblade Gaming PC
MSI Nightblade gaming PC with a quad core I5, 16GB of RAM and an NVIDIA GTX960 Video Card.
With room for a full size video card, WIFI built in, an optical drive slot and a somewhat small case this is a great PC.

Toshiba FlashAir 16 GB WiFi SD Card
I have found using the SD card to be the most reliable way to run my 3D prints, my MAKEiT Pro-M 3D printer also allows me to make mid print configuration changes when printing from the SD card. Apparently the Toshiba FlashAir runs a tiny copy of linux and it lets me upload files to print straight to my printer.Toshiba Flash Air III Wireless SD Memory Card 16GB (PFW016U-1CCW)
