Just want to add/clarify, both mATX SilverStone cases are actually not bigger than the Prodigy. Below is a reorganized list of above mentioned cases based on size volume:
SilverStone SG05/SG06 - 11 liters
Shuttle R5 ------------- 14 liters
SilverStone SG07/SG08 - 15 liters
SilverStone FT03-MINI -- 18 liters
Lian-Li PC-Q25 ----------20 liters
Lian-Li PC-Q08/PC-Q18 - 21 liters
SilverStone SG09 ------- 23 liters
SilverStone TJ08-E ----- 30 liters
BitFenix Prodigy -------- 36 liters
Although the above sizes are true in terms of how much space it takes within a cubby hole, or on a desk, it is not true in terms of internal space without plastics, or so I can only say for BitFenix.
Internally, there is 26.35 liters for the Prodigy. Although there are cases with fewer liters that hold a mATX board, they can compromise in certain areas, such as radiator support, atx power supplies, cable management, 23cm fans, tall CPU heatsinks, or long graphics cards. In some cases (figu, that allow you to put ATX PSU's, but restrict your heatsink to 60mm, or no radiator support, etc.
This is almost the same as saying "My mid tower can hold EATX motherboards", but how much do you compromise? A couple of hard drives? H20 support?
When looking for a small form factor build, there are things to consider. From BitFenix,
willingness to compromise is one of them for Prodigy. Looking for the smallest build you can find? Prodigy might not be your first option. But a GTX 690 + 60mm rad push pull + i7 3770k with 4x SSD's - I don't think it'll fit in a 20L case.
