Seriously wouldn't let anyone else put my PC together. I've been building my own from scratch since I upgraded my first Dell when i was about 22. Not had a single problem with one yet. In stark contrast to some of my friends who bought pre built machines having issues further down the line. Some even had issues from the first week due overheating or peripherals not working properly out of the box...

I would not let any of those overworked underpaid technicians build mine
