Future proof case

[stubbornness]

OK guys so i don't know if you've read my previous questions,but i have a Acer Aspire ax3950, i needed a new GPU and people told me go with the new case+ new PSU+ GTX750Ti, which is what i want to do, but i cant decide on which case i want, my motherboard is a micro ATX, but i want a full size atx case because eventually i will scrap the system in it and get a new motherboard, ram, cpu, gpu and everything other than a case and PSU, what case is fairly cheap (under $100AU preferably lower) and will fit full atx motherboard and you know, fancy computer parts (mainly long or 2 GPUs.

thank you for answering.

Here is a PC I just did with the case:

You can see there are fans around the CPU and it seems there is plenty of room for whatever cooling you want.
