Most of the MicroATX cases have an offset top-left screw like this:
But most of the MicroATX power supplies I'm finding have a rectangular configuration like this:
Which is standard? Are there two standards? I'm trying to build a MicroATX, but I don't want to get stuck with something I can't find a good replacement for down the road.
UPDATE: I will try to clarify my question. When people buy MicroATX cases, which kind of power supply do they usually use? Do some MicroATX cases take regular ATX PSUs? Why am I seeing different PSU screw configurations for different cases sold as "MicroATX"? Is there a norm for MicroATX cases / PSUs, or is it random mix and match between several different types?

The case in question is clearly an OEM case. Which is the reason the screws are in a weird place. – Ramhound – 2015-11-04T13:12:41.210
Some cases have 5 holes, for the regular & offset options. Either way, 3 screws rather than 4 is not going to be any kind of major issue. – Tetsujin – 2015-11-04T14:05:39.733
@Ramhound By OEM do you mean standard ATX? This picture is from this case, which is listed as MicroATX: http://www.newegg.com/Product/Product.aspx?Item=N82E16811154094 It seems to have screws for a standard PSU, but looks too small, so I am confused what would fit it.
– user353885 – 2015-11-04T15:02:01.193@Tetsujin I was thinking of doing only 3 screws if needed, but I'm more concerned with how to if the PSU will actually fit. MicroATX PSUs appear to be physically smaller / flatter. – user353885 – 2015-11-04T15:03:10.167
1By OEM I mean ( Dell, HP, etc. ). I based that assumption on the screenshot, which is a poor screenshot, the manual should have precise PSU measurements though. – Ramhound – 2015-11-04T15:30:05.773
