Is MDG a good place to buy pre-assembled computers?

They are having some promotional sales on their Horizon XL, I was thinking of just buying that for my dad since his computer's busted two days ago. But looking at the technical specifications of that model, it seems that other than the Kingston DDR2 2G RAM, none of the hardwares had any detailed information about its manufacturer or its model number, which made me think that there might be some huge pitfalls in this deal...

However, cramming components together by buying them from NCIX or other local computer shops cost something similar if not more, I never bought a computer from MDG before, so I'd like you experts out there to give me a few thoughts on this deal. Thanks a lot.

Jam it back in, in the dark.

Thanks for your suggestion, I guess I'll just buy the components and install them by myself... it's more secure that way also.

There's nowhere I can't reach.
