A vista basic is not really recc as you cannot do file sharing,
remote assistance ect.
thus, go for a windows media centre edition or professional
edition.
If you must, then wait for sp1 of vista to come out first.
Try not to get a integrated gpu. get a dedicated one about 256mb
shud do the trick. If you do not intend to upgrade your computer
for a long time or you are using it for a long term basis , get a
512mb one.
Ram is more than enough for vista homebasic
Dvd is ok, although i recc LG's Light scribe Dvd burners or blueray
ones if u intend to use this computer for a long period
160Gb Hdd, at 5400 rmp or 7200 rmp? if u must get the 7200rmp, it
writes faster.
