This is a build that is always evolving as the needs for the server change. The OS setup and software setup inside the server is very choppy because it is a first attempt at making anything like this so I am more or less forced to make this up as I go along. The server is used for Plex movies and music, personal cloud syncing between my computers (it acts as a central hub since it is on 24/7), as well as a game server for my friends and I running Minecraft, DCS, and Space Engineers but we are also trying to get Assetto Corsa working (something is going wrong with port forwarding). It also runs a simple discord bot for our server.
This build started when I bought a motherboard for my main system off ebay, following the general consensus at the time that Asus was a good brand to go with because of reliability (spoiler alert, they are not), it came with a processor. The processor in the system was the 2620 that is still in the server. My plan was to sell the processor on ebay and use the 1650 that I had bought. While neither processor is technically supported, certain skews trick the board into treating them like a compatible processor. The specific 1650 I was using and the 2620 both do this. After getting the build and adding my processor, I applied an overclock and hopped in GTA to test how well it works. I was in GTA for 5 minutes and the system spontaneously shut down and would pass post but would crash on the windows logo. Disabling two cores, hyper-threading and down-clocking the 1650 to 2.5GHz would allow the system to boot without issue. I was able to confirm with a second 1650 that the processor was not the problem. It seems that the motherboard spontaneously shuts down with any processor trying to use over 75W of power. I put the 2620 back in and it still works no problem. I was able to overclock the 2620 by a 5MHz base clock increase (crashes with anything more) and with Turbo Boost enabled it can peak at just over 2.6 on a single core and 2.4 on all cores.
I hate the 212 EVO as a cooler as I think it is massively overrated and there are often better performing coolers for the same price or equal performing coolers for cheaper. The only reason that I got this one is that it was the cheapest cooler that fit the 2011 socket that wasn't a top down cooler. At the time the top down coolers were the same price but it would have out performed them.
The server has 32GB of RAM because we were expecting Minecraft to use a lot of the RAM but despite giving it access to 16GB of RAM, it barely touches it. DCS on the other hand, chews through it because of an apparent memory leak. We have it set to reset every 7 days, but by that time the leak seems to have stabilized.
The main drive is the 240GB SSD and my only regret is that I did not get a larger capacity as we are currently maxed out on capacity. I put all of the games on the SSD with the OS to make sure that it would not choke when trying to access data. NVME would be better for this but as far as I can tell it is not supported with this motherboard.
The Hitachi HDD is out of a laptop that had a smaller HDD put in (didn't need too much capacity). This HDD is slowly on it's way out and has already re-allocated 5 sectors. The only thing it is really used for is storing the music library that Plex access, personal files that sync between the computers (they are backed up on all machines so not really important on the machine) and less important files that the server uses such as images and reference files.
The WD Blue drive is the main drive used for movies and TV shows, for Plex. If I ever dabble in using this server as a DVR with Plex then I may look into adding a larger drive for movies and what not and using this one as a DVR drive.
The GTX 750 is only really needed by the DCS server since it has no dedicated executable file for running a server. If it did, a lower power GPU would be used. The 750 is the bare minimum for GPU for DCS and we turned down everything since it is not even really necessary. DCS is the program that is causing the GPU usage to swing up and down in MSI afterburner. I'm not sure why it does that really, I was using a 760 for a while and it didn't (possibly because of VRAM?).
The case is recycled from my old build, it's not an outstanding case, but it's good enough. The problem is that the top of the case is open and it seems to be letting a lot of dust into the system. I am going to close off any opening that doesn't have a fan with tape to try and maintain more positive pressure. The system is kept in the basement and is always on so dust from the near by woodshop sometimes makes its way to the system. There are other places to put it, but then overall airflow becomes an issue.
The SeaSonic PSU was purchased new because I was using some sketchy OEM PSU that I had to splice cables into to make it compatible. I'm not in the habit of burning my house down.
The fans are an attempt to keep positive pressure since it is in a rather dusty environment. All the intake fans have dust filters.
We use team viewer to remote into the server to work on it so that we don't need a mouse and keyboard. It allows me to be more flexible with where I put it. The problem is that it defaults to a 4:3 resolution without a monitor so a monitor is needed for a reference size and because DCS does weird things when there is no monitor.
