I bought this as an experiment to see if I could play games on it.  It did eventually work after a swerve in the road, but we'll get to that later.  First of all for the refurbishment they covered the case with huge black stickers to "refinish" the exterior and honestly they look pretty good.  Sure up close you can tell they're stickers, but from 3-5 feet away you can't even tell at all. 100% would recommend this thing.Now, for the headache with gaming this has nothing to do with the refurbished nature, but a problem with Dell 9020s in general.  I bought a graphics card to put in here but when the PC arrived I saw the power supply was only 290W which is not enough for the graphics card. I expected this to happen so no surprise, but what was a surprise was Dell uses a non-standard power supply connector for this motherboard.  That's super obnoxious.  Anyways there are adapters to convert a standard 24pin ATX connector to the Dell 9020 connector so just be aware if you want to put a graphics card in one of these to play games you'll need to upgrade the PSU also and you'll need to order an adapter for the new PSU to plug into Dells crappy non-standard connector.On to performance, yeah this thing is great.  It's faster in benchmarks than my 2 year old Lenovo gaming laptop because of the better thermal management and a full desktop class CPU and GPU.  You could probably get even better performance with a big aftermarket CPU cooler and fan, but you're chasing diminishing returns at that point.Would buy again.  Turns into a very nice little gaming desktop for less than $500 if you add a GPU and upgraded PSU.
