This was long-overdue, but became a necessity. I finally built a new desktop computer. To make a long story short, I believe my old desktop's power supply died and caused something to short out on the motherboard. After going a month without a desktop (and relying on my laptop for everything), all the parts finally arrived today and I put them together. I'm really pleased with how it turned out.
Here are the specs:
Processor: Intel Core i5-3450 Ivy Bridge 3.1GHz
Motherboard: GIGABYTE GA-B75M-D3H LGA 1155 (SATA III, USB 3.0)
RAM: G.SKILL Ares Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600
SSD: OCZ Agility 3 AGT3-25SAT3 (120 GB SATA III)
Power Supply: Antec BP550 Plus 550W (modular)
Video card: MSI N210-MD1G/D3 GeForce 210 1GB 64-bit DDR3 (HDMI, DVI, VGA out)
I used my existing case, DVD-RW drive, and old hard drive (a 160 GB SATA drive I ripped out of an old PC). Total cost $525.
Like I said above, I'm really happy with it. I love the SSD (I got one of those "My SSD is faster than your HDD" stickers!). Access times are instant. Programs open nearly instantly, and I was able to do a clean installation of Windows 7 in less than 10 minutes from DVD. That's impressive.
