Summary: Had happily bought a Zotac zbox a while ago, and loved it ....until the fan started to wear out (which will happen pretty soon, google for it you'll see). Now, the thing is Zotac DOESN'T sell replacement fans, and they are custom made. So, after a while, you might as well throw the box.
Summary: Cons: Out of box the driver only appeared to support 1680x1050 maximum resolution. Although, the Ivy Bridge is supposedly capable of driving 2560x1440, after some effort, I was only able to drive that resolution at 30 Hz (over DVI). That's completely s***ty.
Summary: I highly recommend you to install two 1600MHz RAM and a SSD. Being very satisfied by its performance, I think it is the only zbox, at this point, to be used as a fancy daily desktop. I connect it to a 27 inch screen with speakers, which finally makes my table clean and tidy.
Pros: flexibility,mobility and performance. Easy to install.
Summary: Packed with features: Intel Core i3-3120M 2.50GHz, 4GB DDR3, 500GB HDD, 6xUSB ports total, 2xUSB 3, DVI, SDcard Reader. Customer: Ideal for HTPC and desktop for the average user. OS: comes without OS, works very well with Windows 7 and Ubuntu derived OS (Ubuntu, Linux Mint).
Summary: I'm using 3 of these in a Linux-based special project where they are asked to a significant amount of processing on a continual basis. Not one of them has crashed yet. And they're almost completely silent.
Summary: This PC replacement works very well. It has all the power and performance of a desktop PC without the size. My only complaint would be the less than stellar outside plastic covers. They appear to be a little cheesy and flimsy. Otherwise, I really like it.
