We have to give credit to Cooler Master for doing something different. Although fresh new ideas don't always work out, we'd really like to see more case vendors give critical thought to their internal layouts rather than just trying to turn heads with dressed-up exteriors. Cooler Master went all-in on this one, yielding the two-level cube/desktop configuration. Not only does this give enthusiasts the option to use this case as a stable test bench after removing the sides and top, but it also means you can stack several HAF XBs on top of each other. They won't even get scratched up, thanks to Cooler Master's durable finish and wide, soft rubber feet.
The HAF XB’s build quality is high throughout. This case is meant as a workhorse. It’s stable, everything sits securely in place, and nothing rattles. Even the PCI slot covers are solid, and not just thin sheets. That might not say much on its own; however, small details like that often say a lot about the workmanship that went into designing a chassis. Another strong point is the front cover's secure fit. You're able to detach it for maintenance. But when it's snapped in place, the tolerances are nice and tight. The sides and top are also easy to slide off and remove.

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)!
