Finally had a chance to pull apart the newly arrived R10 and some food for thought.
Overall
+ Excellent case design that is easy to access common parts, RAM, HDDs (1x 3.5" and 2x 2.5" bays), GPU, front intake fans. All done without screws. Hence, I don't know what's the grudge with online reviews.
- Notorious non standard parts replacement. Will elaborate below, including what's worth noting
The following items were replaced
CPU cooler with a Corsair H60 AIO - perfect direct replacement using the AIO's standard LGA 115X / 1366 STANDOFF mount/screws, no backplate is required. Radiator fits perfectly into the exhaust fan mount. Waterpump draws power from PCEI and fan connects to the exhaust fan connector without any start up error warning. Easily the best upgrade since it is very quiet, and keep the CPU cool. Installation instruction clips can be found online. NOTE - use the LGA 115X / 1366 STANDOFF screws, surprise no online tutorial mentioned which screws to use, or wish that Dell can provide more information on this.
Intake fan - whilst the online community tend to favour Noctua or Corsair fans, I have replaced it with Artic P12 (picked up a few during Amazon sale), and no start up BIOS error.
GPU - offloaded the RTX3070 to recoup cost and purchased a 1070 (3 fans non blower). Big mistake as the mATX case is not very forgiving - suggest to use a 2 fans version. In order to accommodate the GPU, I needed to relocate the front intake fan for more space. Intake fan been relocated to the 3.5" HDD bay using blu tack to secure it - stable and reduces vibration (I am sure there are better ways to do it).
RAM - trying to find after market parts and match the single tight ass stick (OEM part number, costs bomb from Dell, and different timing to retail modules)? Good luck with it… best buying a matching pair of 8GBx2, and sell off the Dell 1x16GB stick. This is complete BS for such a generic component.
Look for X2YH1K-MIE or X2YH1K-MIE NX. Both have the same Dell part number. One is made in taiwan and one is made in the prc.
- Plastic outter shell - Basically stripped the case down as the plastic shell traps dust, is heavy, and takes up space.
End result - a very quiet and decent performing work machine.
P.S - No, I don't feel bad for offloading the 3070 above MSRP, because the person bought it off me thanked me for selling the card so cheaply, and that market rate for 3070 is ridiculous. I have also paid a premium for a very dated card. Simple supply/demand.
Why didn't you just build your own in a much better air flow case then?
