Additional Comments: I'm planning on building an HTPC running WMC 7 24/7 as an OTA 2 tuner HD DVR, and hopefully be able to use the same system to web browse, use MS Office, and occasioally edit home movies nativelly in AVCHD format. My first question is whether or not this is going to be possible an a budget of $850? Second, if it is, is the system I am proposing below work for my needs? Will I be able to overclock with the proposed low profile cooler? Any advice is welcome. I'm not new to technology but this is my first pc build from scratch.

Proposed Build:

Processor:
Intel Core i5-3570K Quad-Core Processor 3.4 GHz 4 Core LGA 1155 - BX80637I53570K - $220

CPU Cooler:
Scythe SCBSK-2000 Big Shuriken 2 (Need low profile cooling for GD05 case) - $44

Motherboard:
Gigabyte Intel Z77 LGA1155 AMD CrossFireX W/HDMI,DVI Dual UEFI BIOS ATX Motherboard GA-Z77-D3H
(is this overkill for what I'm doing?) - $120

RAM:
Patriot Memory 16 DDR3 1600 Extreme Performance Viper 3 Series Kit (PV316G160C9K) - $70

HDD:
Western Digital Caviar Green 2 TB SATA II 3.5-Inch Internal Desktop Hard Drive Retail Kit -
WDBAAY0020HNC-NRSN - $100

SDD (OS):
Crucial 64 GB m4 2.5-Inch Solid State Drive SATA 6Gb/s CT064M4SSD2 - $67

PSU:
Antec EarthWatts EA-650 Green 650 Watt 80 PLUS BRONZE Power Supply (I'm very flexible on this unit,
I just want something powerful enough that is pretty quiet) - $50

GPU:
????? - need help with this. Will the onboard graphics suffice? If not, suggestions within budget please.

Optical:
Undecided, not crucial at this time. BD RW prefered but BD ROM will work, approx. $80 (suggestions???)

Tuner:
Suggestions????

Thanks in advance for any help that can be offered!!!

Have a look at this.

I threw in a new case to fit a better cooler (new case and good cooler are $52 altogether), but if you really want to use your current case and a low-profile cooler, I could change my suggestion. I just don't like the idea of overclocking with a low profile cooler. Most of them kinda suck and most that don't are usually much more expensive than similarly performing tower coolers as well as often have a poor noise to cooling ratio.

I didn't include a TV tuner because honestly, I don't know what to recommend for that. Maybe someone else can be more helpful for it.

The motherboard might be overkill, but if you intend to overclock, a good motherboard is ideal and the board that I picked out, the ASRock Extreme 4 Z77, is a high end board with a lower mid-end price, so it's easy to recommend.

Thank you for your suggestions blazorthon....I would like to keep the case, I choose it specifically to blend with my other A/V equipment. If overclocking would not be feasable with the GD05 i would be okay with that. Do you think i5-3750k will be able to handle the load of a 24/7 DVR and occasional simultaneous AVCHD editing?

Ill take a look at the Motherboard you pick...thanks

I'm not sure because I'm not into that sort of work. The i5-3570K is one of the fastest consumer CPUs available, so I'd expect it to be able to handle pretty much whatever you throw at it, but I can't make any guarantees. If you choose to not overclock (or at least not by much), then you can get a much cheaper B75 or H77 chipset motherboard and be able to fit an i7-3770K into the build's budget that way since you're also keeping your current case. It'd be considerably faster than the i5-3570K for running those two applications simultaneously and would be the best CPU that I can fit in a build within your budget.

Great...thanks i'll look into the i7-3770k
