alright, PSU problem solved, got it tested and working great.
fixed up a couple other things, and i'm just about ready to go!
as for a case, i was probably going to use this, as i can't find too much that would work, it seems:

what size sleeving/heat shrink should I use if i want to do the same, and what should i use as a grommet for the hole in the case i'll have to cut?
