Price History (Excluding Tax & Combo Deals) History:


from completed build My first build

This case is absolutely wonderful! Literally everything is perfect, I found no problems and satisfied me well enough!

from completed build Dual boot build (now Triple boot)

No bells, no whistles, just a solid case with usb 3 - one of the only cases that doesn't look like a transformer dressed as a clown!

from completed build ColonelNicky's first build

Lovely looking case, great internals.

One issue I ran into however was that I didn't want to tighten the Standoffs too tight, which resulted in my Motherboard being too far off. I didn't feel comfortable doing it, but tightening them further made everything fit perfectly.

Included case fans are remarkably quiet. You can barely hear them on the middle fan setting, and you can't on the lowest. I actually moved the front fan up to the higher slot, and removed the upper HDD tray so that I'd have more direct airflow.

from completed build Jack the Ripper

Fantastic case for a great price. Build quality and functions excellent.


I was still worried about AMD cards overheating . I picked this case because of the great airflow, two 140mm fans, and it has fan controller. It's a solid case with great cable management space, and paddings all over the case to reduce noise.

from completed build Sweet Dee - Budgeter's Dream

While a bit more than I had originally intended on spending for a case, I am exceedingly pleased with the product. After spending a stupid amount of time looking into windowed cases and LED fans I decided to forgo the pomp and flash and go with a classier and more refined vibe. Spacious, noise-dampening, ample options for cable management, front and underside air filters, removable HD cages, integrated three-way fan speed controller, front USB 3.0 headers, this thing is damn near perfect.

Really quiet case, very minimalist design (I like!), easy to build in with grommets and cable management spots everywhere, great accessories (e.g. rubber mounts for Hard drives and fan controllers and plenty of sound dampening). But this case is heavy and only two 140mm fans are included.
