Looks as though it could potentially be a nice double viv.
The only concern I would have is it looks like it must have been sitting up there for a long time. That being said you have no idea: what may have been in it, peed on it, defecated on it, or left what kind of viruses behind on it.
So my question to you is with the safety and health of your snakes in mind. How will you be able to thoroughly clean it to ensure it will be safe for them? If it were all glass you could clean it with 1 part bleach to 9 parts water and know that it would kill virtually anything other than crypto but that unit is made of at least two different mediums, wood and glass.
I myself do not know of a wood cleaner that would be safe to use and kill virtually everything. When you do clean the wood portion you will also need to make sure that the finish on the wood is perfect(completely sealed) as any cleaner will get into the wood and then leach out over time. You may want to strip all of the wood down and reseal it completely and then clean it.
The front panels(white ones) I can not tell if are wood or not. If they are something like particle board you will not be able to clean them as anything will have soaked into it.
Just my opinion and some thoughts to consider.
