Input: I purchased this machine 4 months ago. This machine has to be one of the poorest constructed machines I have ever purchased. It only has one tiny little slot for the PCU fan (which clogs with dust) and has no way to open and dust it out. Now the fan is completely inoperable and the machine overheats and shuts down within about 20 minutes.
Output:
Negative Review
