I have a custom built computer system right here. The hard drive will be removed however the latest it held was a 500g for Windows XP. It has among those expensive lights inside the case.
The front panel is loose where you see my finger pointing and is currently being held in location by tape. Aside from that, it's in wonderful condition.
This features the keyboard, computer mouse, and viewsonic flat screen monitor which I think is 19 inches.
