Building an Ubuntu FTP-Server

My student-corporation is in dire need of a new FTP-Server and seeing as I'm in charge of IT, I'm allowed to build a new one.

While I've build several PC's before, I've never actually build a server and I am a complete beginner when it comes to  Linux so I'm not sure whether or not the parts I had in mind are the optimal choice. To give you an idea of the situation:

  • Our university pays for the power bill so I don't care about how much it pulls from the wall.
  • Nobody will care if it makes a lot of noise.
  • Our current FTP-server has no GUI and there is no certainty that my successor will actually know how to work with just an SSH-terminal. So a GUI might have to be installed in the next 2-3 years.
  • It's sole purpose is file-storage for about 20 users.
  • The largest files it has to handle are about 150mb.
  • If you have any more questions, feel free to ask and I'll respond asap.
  • Our ISP is our university and we have about 130mb/s down and 100mb/s up. 
  • There's currently only about 80gb of data on our server. 
  • I doubt I'll be allowed to spent more than 500 euros. 

The parts I would use:

  • APU: AMD A10-6800K
  • Cooler: Cooler Master 212 Evo
  • MoBo: Gigabyte GA-F2A88XM-D3H 
  • RAM: 2x4GB Geil Dragon 1600Mhz
  • PSU:  Corsair C430M
  • HDD: 2x Seagate barracuda 1TB's in RAID 1 (or maybe RAID 10)
  • Case: Aerocool Qs-200 Lite
  • Fans: 2x Arctic cooling F12

I might throw in a Samsung SH-224DB to prevent any issues that might occur while using a usb dvd writer.

Any suggestions, things I should keep in mind, parts that I should (re)consider, etc. ?

 

This is what I would get as the A10 on board gpu power will not really ever be used and the Intel pentium's are low power and don't get that hot.

As I said power consumption is irrelevant so that shouldn't be taken into account.
While the Intel you linked indeed runs a lot cooler, it doesn't even come close to the performance brought by the AMD.
I also stated that we currently use  about 80GB so using two 2TB drives (even in a RAID1) would be massive overkill.

My main concern was that according to logan, the A10-6800k gets beaten by every Haswell when it comes down to anything but gaming. I'm assuming this is because the increased frequency can't come to it's full right due to the small caches when stuck in a memory intensive situation?

If that is the case than I'd probably opt for a i3 4340 which would do fine with just a standard cooler which would eliminate the prize difference.
