Is it ok If I build my computer in the motherboards box temporarily. I have all the parts comign by wendsday, and I want to test them out and use the computer for a few days until i buy a case. I will cut a hole above the cpu heatsink and everything, and the psu and ssd will be outside (no hdd). thanks for your help.
It's usually good practice to assemble and test the motherboard, memory, graphics card, SSD's, HDD's, power supply unit, etc. outside of the case to prove that all components work before permanently installing them into the case.
