Here Prane check this out and its less then $700.00 bucks. Iv built by own pc as well and I only spent $400.00, but its been a few years and I have upgraded the HD to a 1TB and also upgraded my GFX card witch is a great thing about desktops and it does what I need it to do. As far as programs like Office 2007 you will have to buy or find some other places to get it. Also Im running Windows 7 and I half to say it's like having XP on steroids I love it. So I hope this helps and like I said this it specs for a gaming machine, but will do all the things you listed.
The Lay Down:
A. Rosewill R220
An all-aluminum, toolless masterpiece of design the Rosewill R220 is not. It is an eminently serviceable budget mid-tower that will hold all the hardware youâ€™ll ever need in your cheap PC. You should definitely beware of sharp edges when working in this humble enclosure, but you neednâ€™t worry about your rig overheating, thanks to the caseâ€™s many fan mounts. And you wonâ€™t find a better looking case for $20.
B. Stock AMD CPU Cooler
While there are definitely better coolers out there, when youâ€™re operating on a tight budget you canâ€™t beat the low, low price of $0. The stock cooler that comes with the boxed retail version of a CPU is more than sufficientâ€”at least until youâ€™re ready to start overclocking. Stock coolers even come with a pre-applied thin layer of thermal paste, so you need not spend an extra penny.
C. Sapphire Radeon HD 5770
Oh, times are good when you can get technology so current it still has that new PC smell on it. In this case, itâ€™s the scent of our ATI Radeon HD 5770 and its DirectX 11 capability. Even without DirectX 11, this card is a capable performer in DX9 and DX10 games, too.
D. Cooler Master RS-460
The one place you shouldnâ€™t scrimp is the power supply. Sure, there are cheaper generic supplies, but do you really want to trust your precious PC to a power supply thatâ€™s leftover Cold War surplus? The RS-460 provides ample power for our budget PC, and includes all the necessary connectors, including a 6-pin PCI Express power connector.
E. Seagate 500GB Barracuda 7200.12
OK, OK, we know 500GB is a little thin, especially in the days of $75 terabyte drives. But a bigger hard drive is a relatively simple upgrade down the road, and the single-platter Barracuda 7200.12 performs well, despite its low price and modest capacity. Itâ€™s not as speedy as some of the 2TB drives out there, but for $55, can you really complain that much?
F. Gigabyte GA-MA74GM-S2
MicroATX is normally anathema to folks who consider themselves power users, but when youâ€™re trying to build a budget badass, itâ€™s one compromise you should consider making. After all, besides the GPU, what other add-in boards do you use anymore?
G. Patriot 4GB DDR2/800
If technology were a theme park, RAM would be the old-fashioned wooden roller coaster. First, it was so damned cheap that consumers would cry tears of joy whenever picking up 2GB sticks.
H. AMD Athlon II X4 620
Intel may have introduced the first quad-core for the PC, but AMDâ€™s the one who brought it down to a price the average Joe could afford. For $99, the Athlon II X4 620 offers the best bang for the buck available today.
I. Samsung SH-S223C
While there are higher-rated 24x DVD-RW drives out there, in the real world, where thereâ€™s no 24x media, Samsungâ€™s SH-S223C is still a top dog. With great burning and reading performance, and the best DVD ripping speeds weâ€™ve tested yet, this is the DVD-RW drive to beat. You say you wanted Blu-ray in your uber-cheap machine? It just ainâ€™t worth the money, honey.
J. Windows 7 Home Premium OEM
Since the release in October, Windows 7 has received nearly universal acclaim, and for good reason. This is the best version of Windows Microsoft has ever shipped. With kick-ass security and the speed and reliability of Windows XP, thereâ€™s no reason to buy another operating systemâ€”especially when you can buy the OEM edition of the OS for just $105.
This should get you going in the right direction and for the ones that say AMD is shit its more preference then anything. Iv all ways goon ASUS and AMD but that's just me and they never seem to do me wrong. Also with the extra funds you save you can buy your other programs needed for school.
