Corsair 350D supports only Micro-ATX form factor.
Yes, if it is an ATX motherboard. The motherboard specifications should say specifically if it is ATX, mini ATX, BTX, ITX, etc. Most motherboards are ATX.
Yes. The motherboard is ATX and the case is ATX compatible.
usually any motherboard that has a form factor above mini or micro atx (atx, extended atx, super atx) will have atleast 4 if not more expansion slots available by default and normally an atx (and possibly a extended atx) motherboard should fit in a full tower case (a super atx motherboard will more than likely need a super tower)
ATX is the form factor which Motherboards, Computer Cases and Graphics Cards use to standardise sizing. An ATX form-factor Motherboard will fit an ATX Case, and an ATX Graphics Card will fit in the case as well.
9.6 x 9.6
A baby AT will not fit into the same case as an XT on a motherboard
According to the information I have found, the case is a microATX case, meaning it will not support an ATX board.
That all depends. Most Z270 Motherboards will fit.. the case supports ATX, Micro ATX, and Mini ITX form factor boards. But you will not be able to fit E-ATX motherboards.
no it does not have correct standoffs therefore it will not fit you would have to buy a new case with the same form factor (atx,mini atx,extended atx...etc)
The closest thing that standardizes size and shape is what's known as a "Form Factor". Common form factors are AT, ATX, BTX and ITX. The most common is ATX. These form factors specify motherboard sizes and general component placement. For example, you usually need an ATX compatible computer case if you wish to fit it with an ATX motherboard.
Generally, No, ATX boards are 12 inches high by generally 9 inches wide. EATX Boards are 12 inches high by 13 inches wide (see a pattern?). EE-ATX, however, is 13.7 inches high by 13 inches wide. You would need to measure the tray array to make sure it can handle say 14in H x 13in W. I made this mistake. I have a server/workstation chasis, which only handles up to EATX (12x13), and now have a $440 paperweight.
You need to make sure that the motherboard is able to fit in the case first.
