I haven't bought a computer in a looong time. However, the boot sector on my old (9 years) computer crashed. And I didn't have the time to build a new one. One of the HP apps didn't work out of the box. I called Amazon tech support. Huge waste of time. Some women in the Philippines who didn't have a clue ended up handing me over to HP. The problem was eventually fixed but it took awhile. I was impressed that HP had a tech who was willing to work with me for an extended period of time for no charge. It was just the Omen app which I could have done without. Added another 16GB RAM which was easy to do. Adding another hard dive is easy. There are two external slots that you just slip a hard drive into. No need to attach cables. One question in this section asked about the power supply. It is 500 watts.
