My Dad has been using a Dell XPS A2010 for the past few years. Recently it's been getting slow and nothing we do has sped it up. We decided it was time for an upgrade. He really doesn't like wires and wanted an all-in-one so I thought up a part list and told him about it. The massive hard drive and the blu-ray player were things he wanted for some reason. He doesn't do anything too intensive so I think this should last him a while.
I have to say that building an AIO isn't as fun as building a desktop. There are a lot more wires, pretty much nothing is tool free, and nothing really clicks. The build took about 4 hours. I got the Arctic Silver, because I wasn't sure if there was pre-applied thermal paste. There was pre-applied but it was in a grid pattern that I can't imagine being good for the CPU so I applied the Arctic Silver. I figured out that the cooler doesn't require a backplate on the motherboard but you have to put additional standoffs in the chassis to install the cooler. One of the motherboard screws is missing but it's not very important since there isn't much weight on the motherboard.
Once everything was assembled I plugged everything in and booted up. By default the LVDS port (internal video) is disabled so I had to plug in the monitor from my main build to access BIOS and enable it. However there is no manual and this is not mentioned anywhere. We have Windows 8 installed but not set up since I didn't have enough time last night. I will upload more pictures when I can.
