Cooler Master is taking the H-Series with its 200 mm front fan design and shrinks it down to the ITX form factor for the H100. On top of that, this small case includes a built-in carrying handle for easy transportation, all at an interesting price tag to boot.

This looks good. I'm a sucker for cases with 200mm fans. No glass panels is an upside to me. It's a shame itx boards are so pricey.

Edit: After seeing some replies I watched the review by Optimum Tech. The temps aren't nearly as good as I thought they would be. I wasn't expecting it to break any records but a giant fan in such a small space should be sufficient.

how is this a "recommended" when it has quite a number of worrying downsides? owo I think other casings will do way better imo. putting the PSU right next to the GPU & CPU is a big no-no.

Currently consider to build mini ITX as i were constantly move,but these chassis seems mixed bag between cube case and HTPC chassis....it offers cube form factor while keeping low space of HTPC :laugh:
As I browse,these doesn't seem disrupting Thermaltake Core V1 for "performance" metric, or Silverstone SG13 for the looks.Heck, these can't even replace their own Elite 130 in term of bang for the buck.
Another big let down these seem doesn't support DTX,so upcoming Crosshair VIII Impact wont fit in.I'll keeping an eye for any available Fractal Design Core 500.

@Darksaber So is there a good reason why you're still phoning in these reviews despite the fact you've been getting told for months to stop rubberstamping every product as fantastic despite the obvious flaws you don't discover due to your lack of thermal or noise testing?

Shame there's no real feedback mechanism for how lacklustre your reviews are.

The CM Elite 110/120/130 was a great case. I had a 120, that style is one of the smallest ITX you can run and it was still easy to work on.
