Lets see, it's hard to desribe. It's a corner armoure (sp) and there is a place for the monitor,speakers,modem,switch. Then a shelf above that has my games , PC mags and some misc. crap. Then a space for the case, don't like it because it is enclosed and not to much circulation so I keep that door open. Then there is a slide out drawer for a printer but I have my Sub on it and below that some more space for cables,wires,joy stick etc.
It's about 4 feet deep and 5 foot wide but it's 5 sided ( not quite an L shape) so it's hard to figure out SQ Ft, I'd say about 20 SQ Ft. You can close the doors if it's gets messy so that's a bonus.
