Gonna need a fair bit more info than that.
Budget, what do you plan to cool (which will dictate things like required rad space), what are your aesthetic preferences, are you willing to modify the case, are you willing to externally mount radiators. Is there any other general case features you want [/quotems]
budget around $120, windowed, yes willing to mod, dont want to have to use external mounts. something that would fit the " T-virus" reservoir. hope that helps clarify.
