I read that the planet is a flat disc... Pratchett and Einstein seem to agree on that. The cats haven't found out yet or they would be throwing everything over the edge right now.
1) That thing is using a CPU that itself was priced at $309 by Intel (for two cores and four threads).
2) Unless you buy one of the upcoming devices, Chromeboxes are very last decade hardware. And prices never went down

Performance depends on hardware specs, not on "does it have a built-in display".
