I'm using mine for a QSC Touchmix 16 in the QSC rack tray. Fits perfectly, with all ports available.Front has a wireless pack and a power conditioner in the rack spaces, and a router + battery charger for the wireless mics attached to the case. The big "wings" under the QSC rack tray let me store the wireless handheld (in a duct-tape-reinforced paper towel roll, zip-tied and duct-taped together haha).The detachable lids are also deep enough to let me position some additional cases (velcro-ed into place) for my wireless pack, lav mic, clip-on mic, phone connection cables, etc. Stuff that would generally go in a drawer, but not enough room for a drawer with the 2u front.I use mine all the time. I carry it in a crossover SUV with the seats down, but with other cases + a rock'n'roller cart on top of it. It's definitely not a proper truck pack, but it's also not "seat belted into the passenger seat" :)Slight qualms:- putting it back together can be a bit fiddly: because you're inserting a tongue-and-groove joint into another piece that is ITSELF tongue-and-groove jointed to the main case, you have to really align everything right. perfectly fine once you get the hang of it, and the good news is it's not getting any worse as it ages.- the pieces that come off are large (benefit of that is the storage space as above), and they can't be creatively nested / stored. You have two pretty big pieces left to store.- the pin on the back door FEELS like a weak point. it's quite thin, and if it gets bent even a bit things won't align correctly. however, I've never ACTUALLY had any issues with it. granted -- I'm concerned about that point, so I'm careful with it, but not over-the-top careful.... but none of those keep it from being a 5* item (considering the price, that is. definitely better cases available, but you'll pay a lot more for them)
