How much you guys paying for those things?
TigerDirect is advertising a $99 barebones kit -
Mach Speed Viper MK8-939A Socket 939 Barebone Kit / AMD Athlon 64 3200+ OEM / CPU Fan / ATX Mid-Tower Case / 350 Watt Power Supply
Add harddrive ($60), net card ($15), vid card ($35), 4 Lite-On burners ($35x4 from New Egg) and a registered version of Nero ($80), cheapo monitor ($60).
What have we got now, $480? You don't want to reuse your Windows XP? OK, throw a new WinXP into the mix and you're still under six bills.
Whats good is that it's all generic stuff. If something breaks down, you just replace it - you don't have to horse around with a proprietary deal where the parts cost out the gazoo.
Cheaper yet - go with all SATA drives in your current rig and install 4 burners and Nero. Now you're down to just $220, if you already have the SATAs.
