To put this entire project in perspective, lets take a look at my personal home office. You will be surprised at how much can actually fit in such a small space.
I employed the use of a computer armoire and a small used server rack positioned side-by-side.The armoire is just under 4 feet wide and the rack is 2 feet wide, taking up all the floor space available in the closet. In order to allow the bi-fold doors to close, I removed the armoire doors, which would have been redundant to leave on the furniture since the closet doors will take care of the concealing aspect of the design.
And at a height of 7 feet, I installed a vinyl coated wire shelf, providing me with a foot of clearance for storage bins at the very top, and an additional foot of clearance on top of the existing server rack and armoire, which are both about 6 feet tall. This above-head storage space provides room for 16 small bins holding every imaginable office supply I will ever need.
The armoire has plenty of built-in storage spaces above the space for the monitor, along with a drawer for daily supplies and a letter sized filing drawer to fulfill my needs. And for writing space, a double expandable tray that pulls out, revealing a keyboard tray that is 37 inches by 17 inches in size and an additional writing shelf of the same dimensions, tripling the overall desk space when fully extended.
So exactly how much equipment can be "stuffed" into this closet? The numbers are quite impressive.
The server rack holds all the networking equipment (i.e. cable modem, wireless router, multi-port switch, and VoIP telephone equipment) on the top rack. There is a fax machine, color ink jet printer, 3 PCs and 3 UPS units to sustain power in the event of a temporary power glitch. The armoire holds dual monitors and keyboard/mouse sets: one set for my main system and the other set through a KVM switch for the other two PCs. Additionally, there is a digital tablet, label printer, pocket PC dock, USB hub, speakers, laser printer and DVD duplicating machine.
And there is plenty of space to spare!
