background: i've been thinking about upgrading my two 24/7 file servers, G4 cube and pII dell, as my winter projects. while both computers have been reliable, these two systems are already over a decade old. knowing that parts for the cube are not wildly available, and that both computers will eventually fail got me into thinking of building my own pc. purpose: 24/7 file server, ability to clone my current and future mbp's hdd, it'll also serve as a backup computer when mbp is in the shop goal (in the order of importance): recycle parts frm cube/dell, affordable, expandable, energy efficient, 10.5.1 compatible (don't worry, i'll still buy an apple. the next one will be the ultra light weight mbp) parts list: atx case: linkworld 431-06 aka cheap macpro knockoff $44.99@newegg psu: thermaltake pureppower 500W $49.99@newegg ($24.99 after rebate) cpu: athlon x2 be-2400 2.3ghz 45W $99.99@newegg logicboard: dfi infinity nforce4 ultra (maybe $70-80 on ebay?) graphics card: xfx geforce 7600gt 256mb pci-e $87.99@newegg ($67.99 after rebate) ram: a-data/corsair/kingston 184pin pc3200 2x1gb ~$40.00@newegg hdds (4 so far): OS - samsung spinpoint 500gb $105@newegg free shipping NTFS1 - WD GP 1tb (frm cube project) NTFS2 - samsung spinpoint 1tb (on hold, or i'll put in my old seagate 750gb pata) MBP CLONE: maxtor pata 250gb frm dell (might replace it, depends on ultra light mbp's hdd) optical: Sony NEC Optiarc cdrw/dvdrw $25.99@newegg free shipping lan: onboard + pci GbE card frm dell wlan: pci wireless g (frm dell) bluetooh: d-link usb dbt-120 (frm cube) ups: ibm smart-ups 750v (frm dell) thx in advance. EDIT: i appreciate the sentiments you all have expressed towards the knockoff case. however, pic is now taken off cos the focus of the thread should be the hardware configurations of the system.
