This is my first build and I'm very happy with how everything turned out. It's a pretty basic build and has plenty of room for upgrades. As you can see, I don't have a GPU installed, I do plan on getting one someday. The on-board Radeon HD 7660D is actually pretty nice with the 21.5" monitor. For now, I like how the case looks almost empty and like it's almost missing components to make it run.
CPU: I read a lot of good reviews and saw some other first-timer builds with it, plenty powerful.
Mobo: Got it with the APU on a combo deal, pretty basic but does the job.
RAM: Almost overkill for my needs but the price was good.
Hard Drive: Perfect for the budget and plenty of space.
Case: Clean and simple, room for upgrades. There is no place for cable management behind the mobo in this one. I pretty much had to stuff the unused cabling into any open but hidden places near the drives. A modular PSU would've been great to give it a cleaner, tucked appearance.
Case Fan: I replaced the stock exhaust with an Apevia 120mm, it's pretty quiet for how cheap it was.
PSU: More than enough for this setup. I would have went modular but this was a super deal with mail-in rebate.
Disc Drive: Great for the price, pretty loud when running but I've only installed 3 things on disc so it doesn't matter.
Monitor: Great size and picture for how cheap it was, built-in speakers reflect the price but I have headphones.
Keyboard: Cheap, good feel, serves its purpose. It's quiet which is good but I think I'd like a mechanical better.
Mouse: Light, responsive, I don't like the position of the thumb buttons but I have big hands.
Joystick: Thrustmaster T-Flight Stick X with twist rudder
Headset: Sound great for the price, people say the mic sounds good, not good for extended wear.
The main game I play is Aces High II and it's not graphically intense, I put it on mostly all the highest settings and get 45-61 frames while in flight.
This is a very nice complete desktop that destroys stock, off the shelf PCs For under $500.
I already had Windows 7 Home Premium so by default, this is the OS that was installed.
Edit: the last pic shows an old GTX 275 installed, it was not used but the case is advertised to hold up to a 12.5" card.
