THIS.
I went through a similar thing in the past. We quoted a system we weren't familiar. After several phases of replacing incompatible parts, the customer returned the whole lot and went with a different vendor. Sales then blames the tech people for the bad config despite the tech people recommending not to do the config in the first place. You don't want to have that conversation.
Yep. If it isn't in your daily wheel house, you probably shouldn't even attempt it.
I have no issues with guys building a desktop even if a Dell/Hp/whatever is a better buy. But servers are just not something to 'dabble' into.
However, if you do, this would be an ok start:

EDIT: No idea if that cooler will work, but the site says it does.
