TestFreaks posted a review on the HP Pavilion All-in-One 200-5020 Desktop PC

Today for review I have a first, at least for me, it's a desktop PC yes, but it's an all-in-one style meaning that there's no 'tower' section like a regular computer might have, the kind most of us are accustomed to. An all-in-one PC is a fairly new style of PC meant to save space and actually save you some money too. This type of PC has everything built-into the monitor itself, and then you have your keyboard and mouse and that's it. The PC I have today is from HP and it's the new Pavilion All-In-One 200-5020 that features the Intel E5400 Dual Core Processor, along with 4 gigs of ram, a 500 gig hard drive that's all basically encased inside of a 21.5" HD 1080P LCD monitor. Yes it's not exactly a high spec machine, but it's not meant to be, it's meant to be a moderately priced PC with a good set of features, and it is.
