I just purchased an Alienware R10 for myself and it is a nice machine and a serious upgrade from my home built I7-2600k.
Configuration as purchased:
Alienware r10 in Black
Basic ethernet, windows 7 home, 8gb ram, 2tb hdd, Radeon 6800xt 1000watt ps, water cooling, bluetooth and ac wireless.
As delivered:
The same as above but with a Killer NIC instead of basic NIC.
Took one month to be delivered.
Upgrades:
16gbx2 3200mhz ram
2tb WD Black (750) nvme (boot drive) I had to scrounge up my own screw from my laptop parts bin to secure it.)
1tb corsair mx500 (older game storage)
3 corsair ml120 pro 2000rpm fans.
Swapped out front fan and top nidec 120x40mm server fan.
Top fan taken out and water cooler sandwiched between pair of corsair ml120pro 120x25mm fans linked by a pwm splitter.
Water block was reinstalled with reapplied thermal grizzly paste.
Completely reinstalled windows 7 home with windows 7 pro all latest drivers and firmware updates installed.
Machine has quirks:
If you hard power off the machine by holding down the power button you have to clear the cmos to get it to boot back up again. Not doing so gives you an undocumented blink code. (Common complaint on Dell forums.) I had to scrounge my own cmos jumper from an old IDE HDD.
Bios is not latest agesa so you cannot turn on smart access memory in drivers.
Ram needs to be installed in slots 2 and 4 for it to boot and run memory in dual channel mode.
Ram does run at 3200mhz when set in bios.
On the flip side, Machine is MUCH quieter at full load and a little cooler.
I have the fans biased to run at 60% minimum which is almost inaudible but still moving plenty of air. They take longer to ramp to max speed under full load and when they do it is still not so loud as the nidec server fan. (Nidec fan is just obnoxiously LOUD.)
PBO is enabled, 6800xt is not overclocked yet.
Monitor is a gigabyte ultra wide screen 3440x1440 144hz display.
Runs Borderlands 3 max all settings at an average of 100fps+ in all environments.
Would I purchase OEM machine again? HMM... Well... If I was in the same situation with a really old machine that was starting to choke on games and the top tier video cards were selling for twice msrp I guess I would. If things were normal, NO I would not.
Still my kids think the R10 case looks "KEWL DAD!"
