I think my top tips (given to me) would be:
Other than that - ask lots of questions and never stop learning
- Make sure the supply of power is reliable and clean
- Make sure you have the cooling planned
- Make sure your network (LAN/Internet connection) is well maintained
- Find the right space: You may have a noise problem to contend with
Other than that - ask lots of questions and never stop learning
All valid points. I'd also suggest to think ahead of minor details such as PSU cable length (for best flexibility you may want to get 12v GPU power extenders), number of available sata power/molex connectors...etc
Also try not to use molex2sata power adapters (I've got several of those crisped on the 12V yellow cable), get some sata powered raisers instead.
