H61 Compatibility

[Atra1n2]

I'm looking at possibly purchasing an old pre-built system (don't judge me too hard), but I'm trying to figure out what CPU upgrade options there may be. Here is the product specs page from HP:

I'm thinking maybe a i5 2500 or i7 2600 might work in this, but I read some stuff about h61 and h61 express chipsets, and I don't think they're cross compatible. I'm am out of the loop on these older chipsets and boards, so any help would be appreciated.

 

What I'd like to do with a system like this is upgrade to at least a quad core processor, bump up to 8 gb ram, add a cheap ssd, and maybe throw in a cheap video card, like a GTX 750ti or 1050(no additional pci-e power), even though it's pci-e 2 on this older chipset. Are there any issues I may face or considerations I may need to make if I were to go about doing this? Ultimately, I'd like to give it to my nephew to do some light gaming on if I can get these upgrades. Any help would be much appreciated.
