Titan is great, especially if you're into modding. The only thing I don't like about it was that it's all rivetted inside. I managed to take out a couple of rivets, cut a small piece of metal and voila I have a removable motherboard tray.
I've spent the last 3 or 4 months with my PC out of the case though as my original spray painting went badly wrong, got impatient and sprayed too much on which made it wrinkle, had to scrape and sand the entire lot off and redo it. Just got it resprayed now that I've got some time again. I've taken the plastic front off and I'm going to replace it with my own perspex and wire mesh jobby. I've also cut a hole in the base for a 120mm fan pointing upwards.
And I guess my main mod that I forgot about was cutting out a window for it. Have a look at my threads:
The original cutting of the window:

And the new and improved window with spray painting and 120mm fan at the bottom:

You can see the motherboard tray removed and also the front panel has been moved up to the top of the case for easier use when it's to the side of my desk.
Also an idea I'm having of installing an xbox inside the case. It's the perfect width for it. I'll probably get my current plans finished before I look into that though as if I start on that I'll never get my PC back into it.
EDIT: You can also see where I got a 120mm fan to fit in the front at the hdd bay. This works so long as you only need room for 2 or 3 drives. Also the spray painting you see in the thread is the old one, you can see why I had to redo it
