NERD ALERT

After a recent Hardware failure I needed to order a couple of new parts and decided at the same time to upgrade my sons PC.

So I am left with this: Mini Mobo

Basically a basic powered Gigabyte Mobo with inbuilt AMD APU and GPU and I have 4GB of DDR3 for it which I could obviously upgrade.
Nothing special granted but was good enough for him to play Minecraft etc

Now fancy using it for some project, some media thing to sit behind the Telly ? Some old Retro gaming thing?? Not sure!

Help me out :-)

It has no PCI x16 etc just the ol' fashioned traditional PCI slot circa 90's (even though it is only 3/4 years old)

Think it can handle 16GB DDR3 max. (Checked Yes it can)
Nice and small.

What geek fest can I have with it ??

Thanks for ideas.
