Mini ITX would give you the smallest option but may be an issue with finding one that'll fit card length.
For M-ITX,
The BitFenix line of Prodigy would fit what you're trying to do and give you room for optical drives. Also comes in colors and has handles (no experience on how sturdy they are tho).
Bitfenix also has the Phenom line up. Decent reviews, lots of room for an M-ITX. No optical or handle.
Corsair has a line of their Corsair Graphite Series that is for M-ITX, pretty well reviewed and has a handle. Tho no optical.
Corsair Obsidian Series is also well reviewed. No handle but has an optical drive bay.
CoolerMasters line of Cooler Master Elite is well reviewed, has an optical but is no handle for easy carry.
For a M-ATX
Bitfenix has the same line up only for M-ATX as well.
Cooler Master N200, basic black tower case but good reviews.
Thermaltake Core V21 is a cube case. Good reviews, no optical.
