Here's my 34K per day sauce. You can see I don't like side doors or cable jobs very much.
This one is an old mix of parts, with a PD 805 @ 3Ghz, an 8800GTS 320, 1GB DDR2-800 and a P31 Mobo. Runs a single core client and GPU for about 4k PPD.
This is one I built for our roommate/family friend with a mix of old and new parts. This one gives me the most headache; the internet connection likes to fail and it randomly restarts on me. E6400 @ 3.2Ghz, my GTX 260 I temporarily have house in it, 2GB DDR2-800 and a P965 mobo. Runs a VM Linux SMP and GPU for about 8.5k PPD.
In this delightfully tacky case sits the rig I built for my mom, and the motherboard I've come to despise the most. E6400 @ 2.6Ghz, a 9600 GSO GDDR3, 4GB DDR2-800 and a P965 mobo. Runs a VM Linux SMP and GPU for about 5.5k PPD.
Mine and future Sister's:
The one on the left is a spawn of Winter Wonderland winnings and some old parts. An E4400 @ 2.2Ghz, a 9600 GSO GDDR2, 2GB DDR2-800, and an ASrock Via mobo. Runs Windows SMP and GPU for about 4k PPD.
The right one is my pride and joy main rig that I'm typing on now. A Q6600 @ 3.15Ghz, a GTX 260 216, 4GB DDR2-800, and a P45 mobo. The case is the oldest part circa 2003. Runs two Linux SMP VMs and GPU for about 12k PPD.
Last and least:
And I can't forget my trusty ol' PS3. Second oldest client I've been running for about 1k PPD.
