Acer Aspire TC-705 Question about Motherboard and RAM replacement

Hello.
I need to change my motherboard in my Acer Aspire TC-705.
I want to keep current case, so I'm looking for Micro-ATX motherboards. Does anyone know, will any other motherboards with the same format fit in my case?
My current motherboard is "ms-7869 ver 1.0 motherboard" and I don't know if he has the same form factor as the others Micro-ATX motherboards or it's custom?
Also, how can I know which is my current RAM type, DDR2 or DDR3? Because a lot of motherboards with format micro-ATX have only DDR4 RAM, I want to know if I need to buy a new RAM with DDR4 type.
p.s. Please don't send me links to retailers with Acer Motherboards, I don't want to overpay for Acer motherboard and delivery in my country which is too expensive, if I can buy any other which will fit in my case, thank you.
Here's a photo, might be this will help.

Any motherboard that has the form factor DTX should fit perfectly in this case! Also, download the aida64 program to check the ram:

Thank you for answer but I'm not interested in DTX motherboards because it's too small, I guess. Also, probably it won't fit my GTX 1050ti and I didn't find any motherboard with DTX form-factor and 1150-socket available to buy in my country.
