case and cooling questions for AMD XP 2100

[knives]

i have heard that XP2100 overheats very easily. im in the process of building a computer and i am wondering which case should i choose to maximize heat dissipation. do i really need an alluminum case? how many fans should the case have? also i bought my CPU retail, so it comes with a fan. will this fan be enough, or should i switch it to something better?
also i thought i would get antec true power 380W to power everything up.
anyways, please offer some suggestions for a case/fans/whatnot that would make my system stable.
thank you in advance.

if you are not planning on overclocking then the retail hsf will be fine i have a xp 2000 in a regular old case with no fans and it runs at 55c under full load with retail hsf
