Well as far as the time, finishing the wood took the bulk of the time. Between sanding, staining, sealing, etc took about a week and a half. I wanted it to look like a nice piece of furniture in my living room so i took the time to do it correctly. As far as cost it was close to $300. The 3/4 sheet of oak plywood was $50, the 1/4 inch plexiglass was $50, the vents were close to $50, the lights i got from amazon so they were pretty inexpensive. The paver blocks on the inside were approx $2 a piece and the tiles were about the same. So to make a long story short it can get pricey depending on what you want.
