As mentioned, Cooler Master packs a lot of features into its HAF XB. Due to its two-level design, the case accepts all modern tower-style coolers without worrying about height restrictions. Or, if you want, it'll take not just one 240 mm radiator, but also a second 120 mm radiator. The HAF XB also supports exceptionally long PSUs, offers hot-swapping for two hard drives, and features tool-less drive installation. Finally, carrying handles on the sides round out a very LAN party/tweaker-friendly feature set. Perhaps most surprising to us was that Cooler Master has this case selling for $90 on Newegg.

A familiar array of buttons and I/O is found on the front of the enclosure, right at the height where the HAF XB’s two levels meet. There’s a power button and a reset button, a microphone input connector, audio output (AC'97 and HD Audio), and two USB 3.0 ports that are internally connected to the motherboard.
Both the power and reset buttons have integrated red LEDs that let you know when your system is on and when your storage subsystem is being accessed. We like that these are the same color. The internal USB 3.0 connector and cable are black, which matches the case. That's pretty important, given how likely you are to see into the chassis from outside.

Review the prodigy.
Good review, though.
Initially I wanted to go for an expensive 250$ case so my crossfire configuration could fit and have enough ventilation, but then I saw this thing for 125$, bought it and we have been happy ever since.
PROTIP - buy the quietest 120 and 140mm fans you can find or get a fan controller. If you keep the stock frontal fans, you're gonna have a noisy time.
Review the prodigy.
Good review, though.
For a lanparty, yes, the prodigy es better because it's smaller. As a high-end PC enclosure / testbench - HAF XB is way better. My sister used to keep a pair of GTX 480s in SLi in her HAF XB - it's one of the few cases with good enough ventilation for such hot hardware.
Given your experience with this case (and any previous case testing), do you think the HAF XB would cool well with better fans? You wouldn't happen to have the time and a couple of decent Noctua or Thermaltake (the models with the fluid bearing) to test with, would you?
Also, any thoughts on the stock fans rated CFM vs. actual amount of heat dispersed and any impressions with them? My experience with Coolermaster's case fans has been unfavorable over the years.
For the guy who suggested the Bitfenix Prodigy as an alternative to this: what are you, crazy? That thing is a mini-ITX case. It could never pull the duty of this case. It's worthless to any of my needs. Go play with your toys and leave the big boys to talk here.
1. the case only take Cooler master 200mm fans I have heard of some people using work around to fit other brands in, but since there is no "standard" for 200 mm fan's screw hole spacings, its best to get a cooler master brand for the best fit. they do have a really good red led 200 mm @ 700 rpm (non adjustable) also sadly its a sleeve bearing ...
2. when you do install the top fan you lose some range on how high of a cooler you can use. that being 30cm normally the case does fit 180 , but with a top fan in you can only fit a tower cooler that is 150 in height. this is why I haven't gotten an after market cooler for this cpu yet , its hard to find a tower cooler below this size. I however do have my eye on a Gemini low profile (the not so low model) cooler that is leagues above AMD's stock cooler and even offers clearance for tall ram dims., but I avhent had the bread to buy it after blowing my money on the rig itself.
3. last but not leat maybe CM fixed this by now , but at the time I bought this case , the hot swap board had been notorious for killing some Hard drives. On the flip side it is easy to remove the hot swap board all together and just use a sata cable to hook up your hard drives if you fear this problem rearing its ugly head at you which is what I did.

I also have an unusual amount of desktop space, and don't do the LAN thing, except amongst my computers here at home. Even though the case isn't quite designed for my usage model, I have to say - well done CM!
If you looking for a case for pure passive cooling and natural convection this is probably the most well designed case on the market for it yet even though it was designed for a different intent in mind, but you could easily cool a Intel Core i3-2100T in one of these no problem silently with no fans using a good CPU tower cooler, a sdd, and a fanless psu and have a solid dead silent digital audio workstation system.
Don't give up on your e-atx dream! I've had this case since Christmas 2012 and installed an Asus Maximus V Formula e-atx mobo ( another Christmas gift from my better half) in the little beast with room to spare on the motherboard tray. This was one reason I asked for the XB. Btw it is strongly built. I couldn't resist trying what another pro reviewer did-popping off the top panel and sitting on it. Yep, it hold my 185 lbs without a complaint. And, pushing the envelope, I used the frame rails for a few pushups! No sweat for the case. The XB is located on a cabinet right by my desk about two inches below the desktop. Now it doubles as an armrest! Kudos to CM again( wife has a StormTrooper)!
