ADDITIONAL COMMENTS: should be reasonably quiet. I have experience building high end gaming pcs but when it comes to small setups I have no clue what to look for in price/performance. Building a basic computer for a family member who just needs to be online and watching movies. There needs to be no room for upgrade at all, and I have nothing but speakers to start this with. So basically, I need case, gpu(integrated or not), mobo, psu, mouse, keyboard, monitor, os, ram, dvd drive, hard drive, cpu (integrated or not). Anything they will notice as quicker than the windows ME storebought shes had for way too many years now. I am truly begging for help right now, as I am on a tight schedule with this.
