Inverted ATX is simply a case with the motherboard on the other side. The CPU is on the bottom, the cards are on top and facing up.
BTX is ATX mirrored. The cards are on the bottom facing up while the CPU is either on top or off towards the front of the case to get better airflow (Dell design usually). BTX is typically only found in "older" OEM computers like Dell.
Your motherboard is ATX therefor your case is inverted ATX. I don't think you can buy BTX things online.
