I put in 11 hours so far and I'm kind of hooked. I love how you have to problem solve in a lot of these situations. You got to buy the proper graphic card or CPU and try not to forget on putting in the thermal paste when your replace a CPU. And to be honest I didn't know all this stuff until I played this game. I have a friend who builds my computer and I bought this game wanting to have better knowledge about it. So I won't be a complete noob when I talk to my friend when building my next PC.
