I sold my last available case, now I have 3 working rigs and no tower.
Damn my parents for throwing out 3 cases last year and damn DELL for making non-ATX cases. (I was doing a PC repair and the dell mobo needed to be replaced)
I have two ancient cases in the corner of my room. You can have them if you come and pick them up. 
Silverstone SG05
Samsung P2770
Gigabyte H55 mini itx board
8gb of cheap 1333 ram
powercooler 6850
scorpio black 500
i3-550
waiting for Gigabyte p67 mini itx board…
One of them is in a drawer right ?
The tv is kinda on the other side of the room connected with like a twenty foot VGA cable… this is all in my bedroom and the tv sits at the edge of my bed.
As for what I dooooo with it… meh… I dunno… I like realestate. I usually don’t have something silly like this going on but I was working in SDK and found that if I had a monitor for each view (top, front, side, and 3d) plus a monitor free for Interweb for reference pics, forums etc it just makes things easier.
Really its just a toy… I have the monitos and the video cards kicking around so its more novelty than anything.
I´ve had a bit of experience on multimon setups myself, and I find the best way is either 5 vertically (monitors on their sides) or 6, 3 with 3 on top.
Yes… I had a 2x2 before… I’m kinda stuck right now becuz of my “hutch” above… I’m going to be moving to another room so I’ll end up reorganizing
