Desktop Computer Build for $350. NO HARD DRIVE OR CD ROM Needed!

Okay, I had Dell Optiplex GX270 with NVidia Geforce 6200, 4 GB DDR1 Ram which finally DIED!
Meaning, I'm finally going to build my own computer. YAY!
I'm NOT a gamer...I do Adobe Flash and VIDEO EDITING.
However, I do not have much money. I'm trying to build a GOOD computer under $350.

Here are specs I have come up with so far:
1. Motherboard - GIGABYTE GA-H61M-DS2 LGA 1155 Intel H61 Micro ATX Intel Motherboard
2. CPU - Intel Core i3-2100 Processor 3.1GHz 3 MB Cache Socket LGA1155
3. RAM - PNY Optima 8 GB (2 x 4 GB) PC3-10666 1333MHz DDR3
4. Power Supply - Cooler Master Elite 460W ATX +12V V2.31 SATA
5. Graphics Card: Evga GeForce GT 430 1024 MB DDR3 PCI Express 2.0
6. Case - 10-Bay ATX Mid Tower Computer Case - No PSU?
7. Hard Drive and CD-ROM - I will not be buying for now because I will be using the one from my Dell.

So, all of them cost up to $350. What do you guys think? Will it be smooth for my purposes? And will it be better than any new pre-built computers that is at it's price range today?
And obviously, I'm NOT going to overclock.

Thanks.

I wouldn't base a build around a Diablotek PSU. I'm assuming you have a copy of Windows you can transfer over. Anyway, try this build:

Are your hard drive and optical drive SATA?

For your purposes, I think the A6 would be fine, but it is completely up to you. As for the PSU, I recommended that once since it is on sale. It is usually wise to get more than the minimum to account for the fact that PSUs degrade over time.

Edit: Forgot to mention that the PSU I recommended could support Crossfire for another GPU if you wanted to add one in later for the A6 build so eventually it wouldn't be too much.

a sandy bridge onboard graphics may nearly do what you require without the need for a discrete GPU
