Looks good, I love the side mount for equipment. Aspen bedding is so awesome too soI bet you'll like it. Cleaning is easy and when I first brought my 2400gr het ghost girl home the other day I spilled (she knocked over!) her drinking dish and she was super cranky so I didn't want to mess with her much. The aspen soaked it all up really easy so I just pushed it to the side and put some new stuff in there and later (next morning) when I pulled it out it was barely moist. You have a herpstat 2 to regulate but what is actually providing the heat? I will need to upgrade very soon to but my ambient temp in the reptile room is high 70's low 80's so heating is super easy, cooling is the tough part. I look forward to seeing your home made solution for the 41 qt's
