Custom made trolley

My custom made trolley. I have to do this because of three reasons:

1) On early stages photos, it's not shown, but on the right side, there is fish tank. I was affraid of sucking wet air into the system and corrosion. Also I din't want ro risk leakage of fishtank and destroying pc.

2) The PSU whines a bit. I am over-sensitive on high frequencies. It's still hearable, but while on table, it was right at "ear-level" which was driving me crazy.

3) I could place computer on floor, but I wanted to be able to move it when vacuming and it also raises computer, so it doesn't suck dust from the bottom.
