Hi, I'm going to build a second computer and I'm just looking for input and advice! This will be primarily used for gaming, but it will also be doing photo editing and video encoding etc.
Tower: ThermalTake L10
CPU: Intel i7 920 D0 Stepping
GPU: ATi 5870 or nVidia480, might choose to CFX or SLi later.
PSU: Corsair HX 1000W
Motherboard: Undecided, but I want USB 3.0, SATA 3.0, with at least 2 x16 PCI E lanes and good potential for overclocking. Maybe the Gigabyte X58A-UD5? What're your opinions on getting a better board for overclocking and just getting a 3.0 adapter?
SSD: Intel X25-M 80 GB (for OS, all programs, maybe 1 or 2 games)
HDD: Seagate 500 GB 7200.12, will upgrade for more space later.
RAM: Corsair Dominator 6 GB
Cooler: Notcua NH-D14
Thermal Compound: Either Tuniq TX-3, Artic Cooling AS5 or one of the Shin Etsu ones.
Unless you're happy to spend huge amounts of money for your PC to match your modern decor, there's no good reason to spend $850 on the Thermaltake Level 10.
It also seems to have a few cable management and cooling issues.
Why not instead budget 200 or 300 for a top-end traditional aluminum full-tower case and then buy another (or a larger) SSD or HDD?
If you have the budget, you may also want to look into water cooling if you're going to be overclocking the GPUs as well. I think there's a 5870 sold with a waterblock on newegg.
Corsair RAM tends to be overpriced, especially the Dominator series. The current sweet spot for RAM is CAS Latency 7 1333 MHz or 1600 MHz. There are a number of choices in that range, but if you're throwing money around (the Level 10 suggests that you might not be opposed to spending a little more on RAM), there are 3 Mushkin Enhanced 6 GB CAS 6 1600 MHz kits on newegg that are all less expensive than similar Corsair RAM. This kit is the least expensive, at $220 after a $30 rebate.
