Need suggestions on upgrading my HP 110-243w Desktop

[DarthSmoker]

I have this pre built HP, and recently i got into pc gaming. So i want to see what i can do to make this into a gaming pc. Take note that I've never built or modified a pc before.

It came with:

Processor- AMD A4-5000 APU with Radeon HD Graphics 1.50GHz
Installed RAM- 8.00 GB
System type- 64-bit operating system, x64 based processor
Windows 8.1

PSU
External 65 W (100V-240V)

ATI AMD Radeon HD 8330

Hard drive 1TB

I don't think there is much you can do since it does not have an internal PSU.
