The series of desktop PCs by REO covers a vast range of price-power spectrum. Rom Infotech delivered this PC to me promptly and their service was courteous. Please remember to fill up the warranty card and send them a scanned copy, because it comes with a full 2 year warranty. The PC is sleek, and performs very well. It came pre-installed with Windows10 Pro, so testing was possible as soon as I opened the parcel. (But please note that you have to buy a separate Windows 10 license if you want to continue using it). I think the REO range of PCs is at the top of the value chain. The cost is reasonable and the quality is good. Either you get assembled PCs that are cheap imitations, or you have to buy expensive branded PCs. REO connects the best of both worlds.
