I built one water cooled PC and a few others but unless your a gamer it's not worth the cost of an over the counter. Better yet is a good case with Good Mobo/ intel I7 processor for general internet use. The one I'm currently using is new with an Intel I7 processor and a workstation Nvidia Graphics card because I do more graphics than gaming. I put an SSD in it but it didn't work any faster or better so I took it out and installed in in the PC I use for video Work. Them I7 processors are fast. I love em.
The ones I work on are old PCs and Laptops that need repaired for people that don't have the money to get a new one. I'm just trying to help the less fortunate get
buy but sometimes it can be a challenge.
I'll have to check out those Cyberpower PC's They sound pretty good.
