My cheap pc build: $368.94
without shipping and couple parts "Keyboard, Mouse, Monitor, DVD"
Case: $39.99 "included psu in my case" Any cheap budget case.
PSU: "came with case" Atleast 500W "suggested"
Motherboard: $64.99 "I payed 74.99 damnit" Newegg.com - MSI 880GM-E41 AM3 AMD 880G HDMI Micro ATX AMD Motherboard
Processor:$109.99 Newegg.com - AMD Phenom II X4 840 3.2GHz 4 x 512KB L2 Cache Socket AM3 95W Quad-Core Desktop Processor HDX840WFGMBOX
This processor is pretty damn good for the price. The down fall though is the cache. There is no L3 cache. This processor is best left unclocked as well. But with this motherboard above makes it easier to overclock if you really want too. But the CPU should be fine by itself.
RAM: $38.99 Newegg.com - Rendition by Crucial 4GB 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) Desktop Memory Model RM51264BA1339
I chose 4gb of ddr3 ram basically because of price. I didn't have enough cash to afford anymore. But I suggest buying more. I would buy like 4gb x2. Atleast. This is perfect for this motherboard. Because the motherboard is a cap of 16gb. So 4x4=16gb!!!
GPU: $49.99 Newegg.com - PowerColor AX4650 1GBK3-H Radeon HD 4650 1GB 128-bit DDR3 PCI Express 2.0 x16 HDCP Ready Video Card
HDD:$64.99 Newegg.com - SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive
Its a good cheap harddrive. 1TB at 7200 RPM.
