by the look of it if you want to upgraded you GPU you would have to start from scratch since almost all the that computer is custom. The only thing you could bring is the CPU and maybe the ram.
Edit: There one motherboard which is let you bring the CPU and Ram Supermicro Motherboard Mini ITX DDR3 1600 LGA 1150 X10SLV-Q-O
You can pull out the CPU (it's socketed in), the HDD, and memory (SO-DIMM). So you could buy a compatible heatsink/fan, motherboard, power supply, and case. Then buy a GPU card.
The CPU is an older LGA1150 package, so you will need a motherboard that supports that package (Z87, Z97, etc.). The memory is an SO-DIMM form factor used mostly by laptops. There are a few mini ITX motherboards that do use SO-DIMMs, but you will need to check the motherboard specs.
A motherboard like the one below might work. But beware the limitations on the PCIe slot power. GPU cards tend to burn a LOT more power than 25W.

Supermicro also has some motherboards that would work, but they're not cheap (~$175):

Overall, it's not clear to me this is worth it. You might be better off getting a whole new machine (especially if you are not familiar with messing around with PC guts).
