Also.... Why in the world are my pics posting sideways?????
Im gonna presume your using an iOS device aka iPhone or the likes, if so it has to do with their coding they put into pictures, where they have a bit of extra code to say what direction the photo was taken, but keep the photo int he same direction the sensor of the camera sees it at, but when it goes to any non iOS device they don't read that extra code and read the picture how it actually is thus causing a sideways picture. So they went more or less went with a cheap trick to rotate pictures to avoid using processing power to actually flip the images correctly, or at least my assumption of it.
Anyways there are way around it usually you have to edit the photo and manually rotate it, its a very common issue and the fix is a goggle search or two away.
Oh and to the filter issue, is there anyway to remotely locate the fan, aka have it outside the box, and you could always flip the filter to have it be a blow through and located it outside as well, but it isn't quite as effective, and a higher possibility of air leaks "smell", but if the fan was on the outside you can then tuck the filter right up into the top of the box and have more floor space to boot.
