need help with choosing a case, following two cases, are they big enough to fit my current build?? By the way, i use to hang on my laptop( currently using) for some online games for couples days. Therefore, do I need a better heatsink or stock i5 heatsink is good enough (not going to overclock for sure, 'cause dont even know how anyway~~) If I do need a better heatsink, should I change to a bigger case? Again, I want to keep it small, cubic size looks good to me, but definitely not tower size.

I actually specilaise in HTPC/SFFs and LANParty gamers so if u looking for a CFable LANparty gamer:

else just go with an AthlonII X3 435 with that same mobo (there's a combo) and cut down the PSU ^^

Thanks batuchka.

but I forgot to mention a few things: 1) I do want to keep current PSU to maximize energy efficient. 2) I want to get my first build with Intel. It's going to be pricy than your current build. However, as long as it is under $1,000 (i have other parts, optical drives, monitor etc...), I am still going for it.

THe main problem with me is that with my current build, the two cases I picked, are they good enough? I mean, will my build fit inside those cubic boxes? if they do, air and heat flow will also be fine? If they dont, what size of case should i pick, try to be small though...

Once again, thanks for your advice, please help me with this.
