So, finished up Friday, sorry for the late update.

System works great, probably should have gotten a modular PSU so I wouldn't have the extra cable clutter, but there's enough room for it to not be in the way.
The bottom vent was made by drilling holes in a row. I didn't bother marking it and only used the Dell label as a general area boundary to drill as it is on the bottom, and it won't be seen, so the holes drilled are practical, even if they aren't perfectly straight. Near the end though, I changed drill bits because I was tired of drilling so many holes, lol.
Overall, it was a relatively easy mod, especially since I had a stencil for the PSU mount(and my first real case mod). I cut the mount with a Dremel and drilled the holes on target as much as possible, but the holes were slightly wide on one side, so I had to file them down a little to get it to fit.
