Intel NUC5i7RYH w/ i7-5557U Review @HiTech Legion
 

"The NUC is an extremely small device to house an entire computer, with that said expandability is limited to some degree. This particular model has slots for you to install one 2.5" drive and one M.2 drive. Thankfully I think we all realize that we don't need tons of storage with the faster internet speeds available to us and the numerous choices of cloud services for streaming."
