I was looking with high interest between two different full tower (maybe ultra tower) cases, and wondering which was the better bang for the buck between the two.  Those two being the NZXT Phantom 630, and the other being the Cooler Master HAF X.  It just seems that there's probably an equal amount of bells and whistles, and I'm sure this might have been asked before, but it seems that's a rather much of a headache to decide which IS the better one overall.  Just as long as it'll fit a GTX970 (if need be GTX980, if there's good bargains on them from time to time), and as long as it'll cool that along with other things, I'll be cool with that.

Understood.  It's a very common headache for sure...and I've been searching all over Google for this, and it's probably one of the more asked questions when it comes to a gaming case for sure.

Strong Case Filters and Quite:

This case is nice as well.

I usually like customizable cases, but between the two you have chosen, the NZXT may be the best option. The HAF case does allow for future expansion but I do not like it's overall looks.

Personally I don't stray from CoolerMaster HAF cases.

However it should really come down to.. is how many GPU's do you plan to employ.. and how many hard drives?

I have a HAF XM Case with 2-way 970 GTX FTW in SLI, 1 sound blaster recon 3D Sound card and my midtower case only has 2 more slots for expansion cards tied to my Z97 Maximus 7 Hero.

For hard drive bays.. I have 3 SSD's, Two Mechanical drives and I only have one more drive slot till I resort to using my XDoc (Which is dead and currently waiting on its replacement) or putting one of my SSD's behind my motherboard tray. Without that tho I only have one more hard drive bay.. I have the drive which is a 1.5TB drive but I refuse to put it in because I already have one 1TB drive and 1 2TB drive... I have more space than I do files... at this point.

If your going to run 6 or more drives or 3 or more GPU's go with a full tower. If your not.. go with a Mid tower.

This is the backside to my HAF XM. Haven't had much time to play with cables lately tho but this is what I got thus far.

Apparently tho finding my case is near impossible..however the 932 is a nice alternative. My cousin had one and a friend of mine has the HAF X. Massive tower... all comes down to tho like I said, what you plan to do with it.

I decided long ago 2-Way SLi was my personal maximum for graphics.

SLI/Crossfire or not, ive pretty much decided that I will not own a case that's smaller than a full tower, like my Lian-LI, ever again. I actually enjoy working on my Lian-Li. Compared to all the mid cases ive fought with its a pleasure......not a cursing, cutting yourself, cant get your giant hand in the cramped spot, lost the screw in some crazy corner section fight fest, lol. When someone asks metobuild a custom for them and they start showing me the mid case they want, I just cringe inside. Not that I wouldn't do it, but I don't have to be happy doing it!!

I've actually have never cut myself on my HAF XM... haven't found a sharp edge yet.
