I am considering a pc off cyber power - mainly because it turned out to be about the same price as building it myself and I just don't have time at the moment. I was wondering about upgrading a cyberpower build in the future. I realize they cut some corners on various parts (RAM, HDD, PSU, etc), but those are all things I could easily replace over time (though I'm considering changing the PSU right away as I've heard some horror stories...). Is this possible/feasible? I'm on a tight budget right now, both in time and money, so ordering something pre-assembled would be ideal...
