I just received this case today and am very pleased that I placed the order. Maybe a bit long of a read for most and forgive me if I repeat some details already available in the description or on the BitFenix website, but I want to convey why I like the case. First, it measures just under 22.5" x 21" x 10" in each dimension (top to bottom, front to back, side to side across the top front). The bottom air intake (the part that sits on the floor) is very sturdy and thick aluminum and extends solidly from front to back. I was concerned that the case would sink into a carpet and not breathe. There is approximately 2" of open, vertical air space in the intake tunnel (pictured), so yes, sitting on a carpet will allow fresh, cooler air to flow to the power supply without any problems, and dust will be stopped by the dust filter that slides out from the rear. The bottom filter appears to be some type of extruded plastic, so it may require gentle hands when cleaning. The front panel pops on and off with ease and the BitFenix logo is a raised badge (feels plastic) and not a sticker or paint (still covered in plastic in the photo). The pre-installed 120mm (x2) front intake fans are mounted outside the case but behind the front cover and the 3rd 120mm fan is mounted at the rear (all included fans are 3-pin brushless DC fans model BFF-SCF-12025KK-RP). A 140mm fan can fit in the very top of the front, but a 120mm will not span the mounting holes for both top and bottom screws in the uppermost position, so you are indeed stuck with either up to 140mm fans (x3) or 120mm fans (x2). The front, side dust filters are metal filters affixed via screws to the front panel - very sturdy and does not appear likely to fall apart any time soon. There is no dust filter at the bottom of the front panel so it is possible that dust will travel up into the bottom front mounted fan, but with good air flow, air will travel down the bottom tunnel towards the power supply and not in an upward direction into the front bottom fan (hopefully - and I may consider a secondary interior dust filter inside the case at some point in time just to satisfy my OCD). The top panel does slide up and off (with the side tempered glass panels removed) but note that the top panel does extend a little down the sides of the frame (kind of like sideburns) so it seems a little odd the first time you remove the top. The dust filter in the top panel is also metal and permanently affixed. It is covered by the same thick aluminum as the base of the case, but the vertical space is only around 1" in height along the top. If you don't keep them clean on a routine basis, dust will most likely settle into the USB ports [3.0 (x2) and 2.0 (x2)], headphone, and mic jacks since they do face upward and are not covered. I think I will look for some type of port inserts to address this issue, but definitely not worth dinging the case for a whole star (maybe a 1/2 star for the thumbscrews and this upward port design but that is the extent of my issues). Each side tempered glass panel is removed by 4 thumbscrews and feels sturdy. Inside the case there is a lot going on. My only complaint here is that all the thumbscrews are TIGHT and required a screwdriver to remove (and reinstall in most cases). Note that if you want to utilize any of the three GPU support mounts (part of why I bought the case) then you have to make a choice - GPU support mounts with radiator in the top or radiator in the front with no GPU support mounts. There simply is not enough clearance if you are going to liquid cool. With some minor tubing bends you can put the pump and reservoir in the front with the GPU support mounts installed, but not the radiator. Also, if you install the EATX extender plate just for looks, you also lose the proper mounting holes for single GPU support mounts (a 2nd CF or SLI card may be low enough to be below the EATX extender plate). There does appear to be plenty of space for a 26-27mm radiator with either a push OR pull configuration in the top of the case, but not push-pull. I am still awaiting AM4 mobo availability (at least for the mobo I want) so that is a visual eyeball guess, but both the radiator and fans will mount inside the top of the case. There is recessed notch in the top panel that gives available mounting space for up to a 360mm radiator (I put the 3 included 120mm fans in the top just to ensure there is space, and there was wiggle room leftover to slide forward or backward based on other components such as rear or front case fans). I am really looking forward to building in this case once I get all the parts in for my new Ryzen build. Plenty of options for HDD and/or SSD placement, but mine will go right into the showcase RGB lighting panel. BTW, the controller for the included LED panel will require a 4-pin molex connector for power. I hope this helps someone if they have some of the same questions I had before ordering. Two thumbs up for me.
