For cases I generally choose for quiet fans and cable management, most ppl want a window so I throw a windowed case in there (unless there is an amazing deal on non-matching color parts, then I go without a window)
For mobo I choose for the needs of the user (wifi + # of pci slots + quality and typically factor in some sort of customer service)
keep in mind, cases are generally up to the user making the purchase, they could not like your case so it's better to show them 3-4 cases online instead of just being like "get this one" --- of course this is for people not recommending builds on a website, but to friends/family.
