This thread needs another update...
First off i got an older i5 HP desktop for $80. no HD, but a 3.2Ghz 2C/4T i5 w/ 6GB DDR3 1333Mhz. Currently my new games server, because the damn thing idles at 39W.
has 4x PCI-E slots, so i've put my E-sata and USB 3.0 cards in and its my file server now as well.
And the real joy - got myself one hell of a laptop for $175 + $80 for an LCD.
HP G6-2148TX
i7-3632QM (2.2-3.2GHz, 4C/8T)
Radeon 7670 2GB (OC's like a bitch)
640GB HDD (swapped to a 60GB SSD with the 640GB in the optical bay)
8GB 1600Mhz DDR3 1600Mhz
Wifi was wonky, but that was easily fixed - got a 150Mb wiffi N + bluetooth atheros in there now out of my spares.
USB 3.0, HDMI, etc.
Stock clocks while the CPU was overheating before regrease and dust removal.
HP stuck some filter over the CPU fan intake, that more than doubled the noise. smart guys.
Regreased and overclocked GPU:
