Hi everyone, need some advice on changing to a smaller casing (if its possible based on the spec below) because I will be moving abroad soon.

Processor : i7-7700
RAM : 8GB (1 pc)
HDD : Seagate Barracuda 1TB
Mobo : ASUS Prime B250M-A
GPU : ASUS GeForce GTX1070 8GB Strix
PSU : Corsair TX650M
CPU Cooler : CM Hyper 212

I've asked a few shops but they either seemed reluctant to help or do not have the right casing due to GPU size too big. I can change the CPU Cooler to the stock cooler if that helps with space constraint. Current casing is Thermaltake Versa H24 which is too big to fit inside the luggage bag.

I don't have much knowledge in desktop modding but I did some research and I think this casing (http://www.coolermaster.com/case/mini-itx/elite130/) can fit all the parts above? Budget wise, 300-400 but if I can get the smallest possible casing for slightly higher price, I don't mind paying more.

Thanks everyone
