The first thing you should worry while selecting a case is if your motherboard will fit inside or not.. In this case, it'll do pretty easily.. As for the front panel eSATA and/or any other connection, you are right.. If your motherboard does not has those options, you can't use it.. It hardly matters though.. There's always the back panel access..
Most of the current generation cases feature a complete front panel set with audio, USB, eSATA etc.. Firewire seems to be loosing its presence from the front panel nowadays though.. Anyway, although you don't need it right now, but its just a port.. Am sure you can adjust with it fine.. It might come handy in future also.. Though i think with USB 3.0 becoming mainstream, eSATA also might disappear like firewire..
