so I know most of you guys have pretty impressive rigs, but sometimes its hard to tell how big they really are. This thread is for you guys to show off your awesome cases (yes i know theres mod rigs but still)
 
Biggest case i have ever come across is the Antec 1200... UPS guy dropped it off today with a nice hole punched in the side of the box (case only had a scuff but still kinda makes me worry about UPS)
 
Will post pics as soon as my power supply comes in

CoolerMaster Cosmos S is the biggest case I have ever used or seen up close... It was my last build, absolutely massive.

HAF 932 I think I do not need to go bigger for a few years >.>!
Bad enough when I have to clean my components it is like carrying a arm load of bricks.

I have  a Thermaltake Armor+, two Cosmos 1000s, a HAF 932, & a HAF X.  All rather large cases.

obsidian 800d. mine is sitting right next to my bed empty right now and it's almost as tall as my bed.. i can't wait to start loading it up once i get all my parts

HAF 932 is my current case and a large full tower but the airflow is excellent. Had to run some paint on the inside to give it a decent look. Amazing what a little paint will do, check out the pics.

I still use the biggest one I have ever had. It's the Ultra Aluminus Dark Blue. Got it for only $20 on sale at Frys about 2 or 3 years ago. It's a full tower.
                                                   Depth: 18.6"
                                                   Width: 8.7"
                                                 Height: 20.55"

                                    It runs very cool. Very good air flow.

The biggest I have is either the HAF X or an Antec case I ordered years ago.  I don't even know its name.  It is a full tower and has the standoffs for the BATX form-factor.

Silverstone TJ-06 is my biggest case.  My buddy has an 800D and I think its a monster.
 
TJ-06 H x D x W
22.3" x 18.7" x 8.1"

The Thermaltake Armor is the largest and the current case I'm using.  It's pretty heavy as well.  Moving to a mid size Corsair 650D.
 
Thermaltake Armor  dimensions: 20.9 x 8.7 x 22.0 in ----> Fullsize!
Corsair 650 D dimensions:  21.5”  x 9”  x 20.5” in ---> Midsize!

My case (which is the first one I've bought) is an NZXT Tempest EVO and it's 22.8(H) x 10.5(W) x 24.5(L) inches

Haf X big bulky lovable oaf and well worth the buy
 
i wish you much luck with the 1200 =( last time i used it i hated it and the dust filters are a BIG pita to clean

HAF 932.  Anyone who wants a laugh, look at my Mods Rigs.  That's a Micro ATX board in one.

@ OP - that's actually very small for a full tower case.  The largest case I've ever owned is the one I'm currently using - the Cooler Master ATCS 840.  Here is an official picture of it with a 10.5" video card.  It dwarfs everything I've put into it and can easily hold two 360mm radiators.

 
I can't wait to replace it.

Haf 932. I updated my Mods Rigs with new pics, I swear it weighs ~65 pounds
 
but I looooove it <3
