Critique my build

[crafty]

The motherboard on my current rig died, so I'm going to build myself a new quad one. I wanted to get some feedback before ordering. I'm planning to use it for programming, watching movies, playing a couple games (not much tho), maybe some graphics stuff... and just general computing.

1 LITE-ON 20X DVD±R DVD Burner With 12X DVD-RAM Write Black SATA Model LH-20A1S OEM BK - OEM - $32.99
1 LIAN LI PC-7B plus II Black Aluminum ATX Mid Tower Computer Case - $89.99
3 Seagate Barracuda 7200.11 ST3500320AS 500GB 7200 RPM SATA 3.0Gb/s Hard Driv - $374.97($124.99 each) - put in raid 5
1 OCZ GameXStream OCZ700GXSSLI ATX12V 700W Power Supply - $134.99
1 Arctic Silver 5 Thermal Compound - $5.99
1 G.SKILL 4GB(2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL4D-4GBPK - $114.99
1 ASUS P5E LGA 775 Intel X38 ATX Intel Motherboard - $229.99
1 Intel Core 2 Quad Q6600 Kentsfield 2.4GHz LGA 775 Quad-Core Processor Model HH80562PH0568M - $260.00
3 Scythe S-FLEX SFF21E 120mm Case Fan - $44.97 ($14.99 each)
1 Scythe Minebea NMB Silent IC Series 3110KL-04W-B19-E51 80mm Case Fan - $8.99
1 Thermalright Ultra-120 Extreme CPU Cooler - $69.99
1 XFX GeForce 8800GT 512MB PCIe VGA Card - $262

I think the total comes out to a little under $1,700.

I chose the case because it looks nice and there'll be a 120mm intake fan right next to the hard drives. I went with the asus motherboard b/c it seemed to support overclocking pretty well and supports raid 5. I tried to pick out quiet fans... I'm going to replace the fans on the case with the Scythe ones. I picked the hard drives b/c they're good size and have 32-mb caches (I think I'll have just under a TB on the raid array).

A few questions:

1. Will the Thermalright Ultra-120 Extreme heatsink fit in the lian li pc-7b plus ii?
2. Do all the Q6600s overclock well or do I need to get a particular stepping?
3. What wattage psu do you think I need for this? 700 is probably overkill no?
4. How loud will the geforce 8800gt's fan get?
5. Anybody hear bad things about the Seagate 32-mb cache sata 3.0gb/s drives?

Oh yeah, and I'll be running Ubuntu on it with 2 24" dell monitors that I already have.

ok, i'll check that out.

does anybody know if the raid on this motherboard is real? or is it software? i can't find any clear info on this "matrix" raid. i suppose that if the motherboard fails, i'll have to find another with a similar chipset to read the raid array?
