Help picking new motherboard

[BanderSnatcher]

I need to get a new motherboard for my HP Pavillion a1050y. I was extremely close to ordering a motherboard I thought was okay until I googled the dimensions of it which was 13'' x 10''. I measured the dimensions of my current motherboard and it was 9.6'' x 9.6'' so I'm not really sure what kind of motherboard I should order. I looked up Motherboard sizes and a website classified 9.6'' x 9.6'' motherboards as for 'Specialty PCs'. Does this mean I can't use a custom motherboard for my computer? Or do I just use a microATX motherboard?

You will need a microATX board.

Here is your motherboard specs.
