first off let me say that im seeing a lot of conflicting reviews on here. some say its way too small and other say its too big while others say they did not get the same case that is in the picture. i received the same pc that is in the picture. as far as the size it is very small but that is just what i wanted because it was for my mother and space is an issue. the computer is 11 1/2 inch tall, 12 inches long and a little under 4 inches wide. its a powerful little pc with a true 4 core i5 cpu not the 2 core 4 thread version. 8 gig of ram in the form of 4, 2gb ram sticks. the pc worked right out of the box, i didnt need to setup anything it just booted to the desktop. it came with the 2tb hard drive and takes about 35 seconds to boot to desktop. since my mother has no need for 2tb of space i took out the drive and put it in my kids gaming pc for extra space and replaced it with a $20, 128 gb solid state drive. it now boots in 14 seconds. the only issue i have and its not a problem really is the mouse they sent me with it was broke with a huge crack on the bottom of it. its a cheap $3-$5 mouse anyways and i have plenty of extras here so like i said not a big deal but would be nice if they did a quick visual inspection before sending it out. i give it real rating of 4.5 stars with the half a star missing due to broken mouse.
