any suggestions on specific parts for this? Basically what I need is: Pref AMD X2 although Intel is 'ok' 2 SATAII hot swap - or at least external bay removable - these will be mirrored <maybe 3 drives and Raid5 - suggestions?> <possibly the boot drive in a bay also> 10/100/1000 Ethernet 1 gig RAM some basic onboard video costs? Any suggestions for alternatives are also welcome. This is going to be a colo box for some basic web hosting, email and a bit of ASP(app service provider). The 1U is based on the cost of colo space. also... All linux raid or mobo hw raid? get a separate card? what is the decision criteria? With what types of Raid (kernel, mobo, card) is it possible boot off the raid vs need a boot drive Any suggestions on colo space and costs? all hardware needs to run under linux kernel 2.6 FYI: I need to get the hardware purchased very soon.
