Next to a notebook, an all-in-one is the most difficult type of PC for a DIYer to build, simply because no one’s manufacturing enclosures capable of housing both a large monitor and the guts of a computer. Pick up Zotac’s ZBox Nano AD10 Plus and you can put together the next best thing: A computer that can hang off the back of almost any display you like, thanks to the included VESA mounting plate. The AD10’s dimensions, near-silent running, low power consumption, and generous I/O options render it a good choice for a disc-less home-theater PC, too. An HTPC that can’t play Blu-ray discs might seem gimped, but Vudu’s on-demand service is a much better alternative to renting Blu-ray movies from Netflix; and if you’re a collector, you should rip your movies, store the disc images on a server, and put the originals away for safekeeping anyway. The AD10 has plenty of horsepower for watching HD video and running lightweight applications, but don’t expect to play anything beyond the least-demanding games on this box. The AD10 is based on AMD’s dual-core Fusion E-350 CPU, running at a stock 1.6GHz. The E-350 features an integrated 500MHz Radeon HD 6310 GPU.
