No, it's really bad.
Keep the case if you like, the horrible cheap green plastic isn't to my taste, but if that's your thing fair enough, the case itself isn't bad.
The motherboard is probably the weakest link, the 780i chipset usually lasts around 6 months and is really unstable even when it does work. The Power supply is also poor and the graphics card mediocre by modern standards. On top of all this, I don't trust OCZ RAM, it seems to go wrong a lot. The Hard disk and CPU are about the only good parts of that build.
Use a Gigabyte EP45-UD3R Motherboard, 2x2GB Corsair PC2 8500 Dominator RAM, a Sapphire Radeon HD4850 graphics card, and a Corsair VX 450W Power supply, keep the rest if you like.
450W is plenty for that build, don't worry.
Everyone has problems with some brands...Sammorris does not like OCZ ram (I usualy go for Corsair myself, but have had good luck with the OCZ ram I bought for my laptop)...I don't like Samsung hard drives (out of 4 I purchased in the last 2 years, only one still works...and it has bad sectors; all four were outlasted by MANY older drives). The processor is also a weak point; for the same price you can get a quad-core 2.6GHZ AMD unit on newegg.com. Intel is faster if you have money to spend, but for a box like this, AMD will give you a better bang-for-the-buck. {INTEL GUYS: THIS IS WHERE YOU ADVISE HIM TO BUY A $800 INTEL QUAD-CORE}
One other thought...I don't like case doors; burners eject on their own after a burn, I lost a plextor burner when it tried to eject & was blocked by my chair...I assume the same thing would happen if it was blocked by a case door.
OCZ RAM for laptops may well be fine, but OCZ Platinum desktop RAM is known to cause issues. There are always those that put down a brad because they simply don't like them, but when you hear the hundredth horror story about a product, you listen.
On an $800 budget, it makes sense to use the extra performance gained from an Intel CPU at the time of the post. AMD fans are rare and welcome, but AMD fan boys, not so much.
