Upgrade Processor on 77521QU - H420 desktop

I have a 77521QU  -  H420 Desktop with a Intel G620 processor and wanted to find out what other  LGA 1155 processors will work. Can't find any data but this is what I'm considering installing.

Intel Core i3-2100 Sandy Bridge 3.1GHz 2 x 256KB L2 Cache 3MB L3 Cache LGA 1155 65W Dual-Core

 

I see other H420 with the i3 - 2100 CPU but not sure if it is the same motherboard.

According to the PSREF for Essential Desktops

H420 (7752) at

It looks like the motherboard would be the same.

I am not 100% sure, but I see nothing that indicates

that there are different MBs.
