That question has a lot of variables. There are big differences between acrylic and glass in every aspect. It is possible, if you have a garage with some basic woodworking tools (especially for acrylic) and you are mechanically inclined at building things.
I would recommend some research, and educating yourself. The whole procedure is way to much for a venue like this.There plenty of info on the web to make an educated decision. I have a video course coming out (inexpensive) in about a month that will detail filter building. The techniques are the same for an acrylic aquarium. Leave me your email and I will notify you when it is out. Please ask any specific questions that I can answer here4 and I will be glad to.
