OK, after mucho work, I've come up with what seems to be the best bang for the buck for my video conversion client who needs new systems.
Here's what I selected:
Antec DF-85 Black ATX Full Tower Computer Case (tons of space, USB 3.0 ports, CPU cooler cutout, 9 internal 3.5" drives, 7 fans, long video cards fit) - $156
CORSAIR HX Series CMPSU-1000HX 1000W Power Supply (any chance I need more than 1000W?) - $230
ASUS P6X58D Premium LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard (Note: only available board supported by BlackMagic for their DeckLink/IntensityPro video capture cards, so this is pretty much it unless I want to chance a non-supported board with equivalent specs) - $290
Intel Core i7-950 Bloomfield 3.06GHz 4 x 256KB L2 Cache 8MB L3 Cache LGA 1366 130W Quad-Core Processor BX80601950 (I intend to overclock to some degree, probably under 4GHz) - $270
Prolimatech Armageddon CPU Cooler - Intel Socket LGA 775/1156/1366 Heatsink, 140mm Fan Compatible (Selected this one because one Web site review of the ASUS board specifically used this cooler which fit nicely without covering up the 6 RAM slots; also this one gets good reviews everywhere) - $65
XIGMATEK eXTREME SILENT Series XSF-F1452 140mm Case Fan x 2 (for the above cooler to improve cooling) - $20
G.SKILL Ripjaws Series 24GB (6 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL9T2-24GBRL - $285
Palit NE5X56T01142-1041F GeForce GTX 560 Ti (Fermi) 2GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card (lots of DDR5 RAM, 384 cores, 256-bit memory path, well reviewed) - $280
SAMSUNG Spinpoint F4 HD322GJ/U 320GB 7200 RPM 16MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive (for OS and programs) - $43
SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive x 4 (for RAID 0) - $260
SONY Black 12X BD-R 2X BD-RE 8X DVD+R 5X DVD-RAM 8X BD-ROM 8MB Cache SATA Internal Blu-ray Burner Blu-ray Burner BD-5300S-0B - OEM - $110
Link Depot 39.37" SATA II Cable with Locking Latch Model LD-SATA-1 $4 X 5 Drives + DVD Burner - $24
Total Cost: $2033.00
With Windows 7 Professional OEM and an Adobe Premiere Pro CS5 upgrade, that adds another $434 making a total of $2,467. I think the client can handle that. He will also probably get a Matrox MX02 Mini or a BlackMagic DeckLink/IntensityPro card to handle video capture. I'm leaving that decision up to his tech. If he needs to go to a full CS5 Production Suite, then he needs to tack on another $500-600 over the Premiere Pro upgrade price which will bring him up to $3,000 for the whole system.
He needs to replace three machines in the video department, but my guess is we'll start with one, maybe two, and the productivity improvement over the crap he's using now may mean he doesn't need a third one. Considering he's upgrading from six-year-old+ Pentium 4 machines with 2GB RAM, no RAID, Adobe Premiere 1.5, these new systems should come as a shock. Hopefully the price for the upgrade won't be as big a shock.
I welcome any comments on the system laid out above, positive or negative.
I know I could improve this slightly with say, 10,000 RPM Velociraptors for the OS drive, and stuff like that, but I've tried to keep this pretty vanilla to hold the cost down.
Let me know what you guys think.
