Ive got a few machines at home and im wondering which one would be best left on 24/7 to use as a torrent machine/media server. Machine #1 Dell GX270 SFF PC P4 3.0Ghz (Prescott) with 1Gb ram and onboard video (865G chipset). 160Gb Hdd 160w PSU (As there is not enough room on this PC, ill also be connecting an external 400Gb 3.5" hdd to it). I could put the 400Gb instead the PC, however i figured it would be handy to have it as an external incase i needed to take it somewhere). Machine #2 E8300 + Gigabyte EP31-DS3L + 2Gb Ram + 7600GT WD 500Gb (AAKS) hdd + Seagate 320Gb hdd Enermax noisetaker 430w PSU.
