Creating a Linux Game server computer?

Hi, me and my freind is teming up to build a shared game server and i need some support
We are using theese parts
CHASSI: Define Node Black ( the small version not the big new one)
MOBO: Gigabyte GA-F2A88XN-WiFi
RAM: 2133MHZ 8GB CORSAIR Dominator
CPU: AMD A10 7770K FM2+
PSU: (might get hate for this) An old 450W psu that has served my freind for many years without any problems whatsoever
GPU: Intergrated
SSD: 180GB Intel 530 Series
OP: LINUX 64BIT
Cooler: NUCTUA NH-U12S ( Does this even fit?
Internet: 100/10 mb/s Fiberoptics

Does linux run Minecraft, Ftb Terraria servers etc.. Well? Does it require much knowledge and hows the performance?
Also. The Ssd, Ram and Cooler can be changed but not the other stuff becouse of reasons..
So should i change anything?
This system needs to be silent becouse it will sit in my bedroom on 24/7
Thats also why we only have an ssd.
How much Space does linux take?
Watercooler is very expensive and the pump can be very loud and the stock fans usally sucks..
The noctuas has the top teir fans.. noctua ... and they are very efficent. it should fit inside right?

thats how to setup a linux minecraft server.

depending on the distro they range in install size but ubunto is about 1.5gb on disk and about 5 once installed.

nothings fully silent not even water cooling theres always a slight hmm. just get a decent cpu cooler with large low rpm fans.

So a noctua nh-u12s? my nh-u14s is not hearable so if it fits i'll get that

I'm not sure if that cooler will fit. If that does not fit, try the NH-C14. Most server programs for Minecraft should work since they are mostly JAR files which are compatible with any OS with Java.

the chassi is very tall and supports a 160mm cpu cooler or somehting dont remember..but what it doesent support is wide short coolers becouse it takes up the entire surface of the mobo and it interfears with ram and the psu

According to the Noctua website, it may fit just right. Noctua.at - sound-optimised premium components "Designed in Austria"!

Well... sound promising... JUUUUST right. this will be fun

A quik question what operating system is best for a game server?
Linux, Ubuntu Or Ubuntu Server?

Ubuntu is a Linux distro, with MC servers, I don't think you have to go for a server OS. Ubuntu Client not server would be the best.

okey. Thanks
