Looks are strictly personal preference i guess.. Like personally, i find the HAF series among the ugliest cases (922 is less ugly as compared to the 932, again personal opinion).. That way the Tempest Evo is much smarter.. Both provide similar cooling i guess although the HAF with lesser but bigger fans should be quieter (not sure).. Personally if i need to choose strictly among those two, i'd choose the Tempest.. But given the same price bracket and no restrictions, i'd go for the CM 690 II Advanced..
