meh, i think on last computer it took about 12 mins or so to install xp, another 3-4 to put drivers on. download them onto diff partition before reinstalling windows, you don't have to do a chipset driver, then reboot, then sound driver and reboot, then lan and reboot. somehow i've never once had an issue doing it all in one go
the installing generally only a couple of the latest games i've been playing. built computer to playing first game can be sub 25 mins quite easily on XP now, i do remember installing it on a 1.4tbird, with 512mb mem and a slow hdd though, not quite so fast

raid 0 seriously seriously helps with install times though.
i dunno, i never ever connect front panels as if i must i have one usb extension cable from the back that i hide round back of monitor for when i need it. errm, generally the only thing i find irritating is poorly design hdd mounting, and hdd's sticking out over mobo only to upgrade gfx card and find you have to move a hdd or two around so a gfx card can slide into its slot between drives at the end of the card.
antec 900, great case mainly, too short for multidrives + 8800gtx though, and its hard drive mounting is truly the worst i've ever seen. why they can make a sonata(trays you screw drives to outside case, with rubber grommets, with sliding click in trays that take seconds to install. to the crappy bays on the 900 case i do not know.
