Revit does not play nice with Intel graphics (I'm guessing the same goes for Naviswork) as you have in the first option. The GT1030 has 2Gb of memory, so that will be OK for Revit/Navisworks

Having just 128GB of SSD in the second option is a bit low if you ask me if I see the list of programs you are going to run. You want them all on an SSD if you ask me.

i5-7500 is faster then the i5-7400 (3,5Ghz compared to 3,4Ghz) and faster is better.

So, it looks like you have some components from the one option and some from the other I would choose if I had to make the choice between them.

But it all also comes down to what kind of models you are going to be viewing, are they small 2 story houses, or large 30 story skyscrapers? If it is the last I'll get something a bit better.


Going by the lack of Intel graphics I would go for option 2, but if I had another option I would add a bit more money and get something just a bit better.

128GB primary drive is too small. I would suggest at very least 256GB. The Dell has the better video card which will be better for Navisworks.

I built my own Box with these requirements at roughly $850 (w 64bit OS) (see specs below). Buying a from a Typical Electronic Retailer that builds them w lowest quality parts & Boxes that are quick dust collectors or from a Custom Build Retailer (I'd recommend Origin, MSI, or "BIM Box") (not so much dust collector Boxes) that has too much overhead that I'm willing to pay for. Ya, you have a warranty w a Retailer, but they are more for "accidents" in 1st to 2nd year that never happen with quality parts. I prefer to do it myself with no overhead & best quality "bang-for-the-buck" parts that'll last more that a year w/o loosing performance (also, dust=+heat=+degradation; Boxes I get req way less frequent dust cleaning of interior). Been building my custom PC Boxes & for friends since '02, so I know a thing or two (followed by the State Farm Jinggle, lol).
