I bought an assembled computer there, and it was a pretty good experience.
a) They have almost all parts available
b) They assemble it within one and a half hours, including windows installation
c) They ship it to your place within 3 and a half hours, which is a pretty damn good turn around time for a computer shop operating at brigade road :D
d) Don't look around for accessories, if you're a gadget freak... you'll buy a LOT from here.
