awesome progress I ilke the look of the exposed PSU, you did well there. Soldering, yeah that was a bit of a mess but don't worry about it, it will be fine. Resistance is SFA. in future you should twist the wires together, there's a knack to it, but it makes a stronger join and better contact when you do it right. PSU fans - I think you should put one more on there just to be safe, I would try to mount it horizontally to blow air down on the PSU. Might be tricky but give it a go. Lastly teh bluetooth adapter. I think you should be able to jam it straight into a USB port. if it is loose cut some slivers of plastic and jam them in there - the tension on the pins should hold it in place. And then put some hot glue in on top to keep it there. If you don't want to ruin your usb port, get a short extension cable and stick it in there.
