I have used two folding tables for my workspace. One is a 6 foot and the other is an 8 foot table. On the tables I have plenty of workspace, my computer, monitor, scanner and multiple hard drives along with Cricut.
Above the table we installed the short version of the HomeFree shelving unit along with shelving. You can also see my two Clip it Up towers that house all my themed and rainbow papers and large embellishments.
Above my tables I store things that I use all the time (I will have close up's later on). I store brads, paints, adhesives, tags, my prisma markers in the two shelving systems above.
