Can someone sort out my confusion?

I have an old case that was micro atx sized and I wanted to make into a server but I have one guy telling me I can't use micro atx because it will fry itself and fall over but another guy saying its nothing more than a smaller atx board which most people use for a server so it would work just as well. Also it was going to be for a minecraft server.

My internet keeps disconnecting on certain programs?

For the past 2 weeks i have been facing a problem with my internet, it keeps disconnecting on certain programs. On steam, every 15-20 minutes it will go offline and i won't be able to connect to any game server or talk to friends (same with origin) and on the game minecraft i won't be able to connect to any multiplayer servers. This problem has been making me quite mad recently and i have found no way to fix it. If someone could please help me it would be very appreciated. (I own a desktop that uses Ethernet, and the desktop is almost brand-new).
