I built this computer to be a general server with a small footprint, which it accomplishes quite well. I also have the option of upgrading the ram in the future, because I knew that would be the first part that would need to be upgraded. I also didn't include a price for the hard drive, because I ended up using a 500GB Western Digital I had lying around, I'll get around to getting a better one later.
It's been running for a couple months now, and I haven't had any (hardware) problems with it. The fan gets pretty loud when under high loads, I just went with the stock air cooler, but that usually only happens when something crashes. Also I can't seem to get it to consistently boot after a power failure, it seems to be about 50/50 with that, so I have the reset button hooked up as the power button so it doesn't get bumped accidentally, but I can still turn it on when I need to.
