The Dac is excellent, the difference from the computer/mobile DAC is more than noticeable.

This model is a Dac and Headphone Amp combo. It connects to the computer via a USB B cable and does not require external power. The headphone port in the front is 6.3mm, while the classic RCA output is available in the back. The headphone output and the RCA output both work continuously, without the option to deactivate either.

There is also a light that changes color depending on the quality of the music it receives. It is not particularly useful, but it exists.

It is used together with a pair of Hifiman Sundara. The Zen Air Dac does not alter the sound signature of the Sundara at all, and the volume levels are more than satisfactory. The "Power Match" button is what provides the "power" required for high impedance headphones or Planar in this case. The other button that this Dac/amp has is the "X-Bass". Surprisingly, the X-Bass is a very nice addition. It enhances the low frequencies without eliminating the rest, and especially in combination with open-back headphones, it greatly helps in "recovering" the bass that they lose by design.

For 100 euros, it is a very good choice for someone who wants to enter the world of hi-res audio for a small amount of money. If another amplifier is purchased in the future, the iFi Zen Air Dac can be used as a DAC that sends a signal to another amplifier.

The Logitech G923 is the generational upgrade in the Logitech series. Compared to the G29 (and the G920) it replaces, it has more precise and powerful force feedback, while the pedals have been upgraded to provide a more direct connection to the game and resemble real car pedals. Otherwise, the visual difference is purely aesthetic, as the G923 sacrifices the blue and red accents of the G29 for a more minimalist and simple look.
The steering wheel is incredibly high-quality, with leather on the wheel, very nice paddles for the gears that resemble the sound of a mechanical keyboard, and a moderate to good feel on the other buttons. The RPM meter returns from the G29, but although it is beautiful, it is not particularly useful, as during driving you don't look at the RPM meter to change gears, but rather listen to the engine.
The pedals are equally high-quality, with the two outer pedals (clutch and gas) requiring the same force throughout the pressure, while the brake requires more force as it approaches the end, just like in real cars.
The Force Feedback (which Logitech calls "Trueforce" for the G923) is very satisfactory and powerful, even in the moderate settings of the games I have tried (F1 2020, WRC 9), and it gives you a very good idea of what is happening with the monocoque or the car.
As for its competitors, the G923 often seems to not be recommended, and instead the Thrustmaster T300RS is recommended. As for the T300RS, it is qualitatively worse, not only in terms of appearance and feel, but also in terms of functionality, as it suffers from a known problem with the power supply, which heats up and burns because it is integrated into the central board of the steering wheel. Additionally, the pedals of the regular T300RS are much worse than those of the G923 (both in terms of appearance, feel, and quality), resulting in the need to spend an additional 50 euros to acquire the T300RS GT. Certainly, Thrustmaster has a 1080-degree rotation compared to the 900 degrees of the G923, but from my experience, 900 degrees are more than enough for 99% of the population. Finally, the Force Feedback of the T300RS is certainly more powerful, but that of the G923 has a much more direct and "fast" feel compared to the T300RS. Furthermore, after a certain point, the force feedback can have a negative impact on the game, and this point is covered by Logitech. There is no reason for a more powerful force feedback than what it offers. In my opinion, the T300RS (GT) is not worth it. The regular G29 is priced at 240-250 euros, where it is worth spending an additional 40 euros for the G923.
Finally, it is possible to change the steering wheel with a Custom Made one if desired.
The mounting mechanism is very understandable and sturdy, and the pedal set has anti-slip pads if you plan to place it on a flat surface, as well as a special surface if you want to place it on a carpet.
The only negative thing I can find about the steering wheel is the dpad, which often initially registered wrong inputs, but after a few hours, I got used to it.
The "Logitech G Hub" is the Logitech application for the steering wheel and allows you to change the sensitivity of the pedals, create macros, limit the rotation of the steering wheel, and much more.
In the end, the G923 is a very good steering wheel, with very good force feedback, and very high quality. It often goes on sale for 250 euros, where it is well worth it, although its usual price is around 290-300 euros. The steering wheel is suitable for beginners and experts, and makes a big difference compared to a controller.
Attention, make sure to choose the appropriate model of the G923 for your platform (PS4, PS5, PC) or (Xbox, PC).

The NH-U12A is the best cooler from Noctua in terms of performance/size. The NH-D15 is on average 2-5 degrees cooler, but it is huge, doesn't fit in most Mid-Towers, and has poor RAM compatibility.

In a Corsair iCue 220T case with Vengeance RGB PRO RAM, the NH-U12A fits perfectly and keeps the Ryzen 5 3600 at incredible temperatures. We're talking about a maximum of 71 degrees Celsius in Cinebench with 10 runs and 4.4GHz all-core OC @ 1.3V. The best part is the sound produced by the cooler. There is none. It is completely silent, to the point where you have to check to make sure it's working, even under heavy workload. Noctua includes "Low Noise Adaptors" in the box, cables that allow the cooler to run at 1700rpm instead of 2000rpm for extra quietness, although I didn't need them. Noctua also includes a whole tube of NT-H1 thermal paste in the box, which is enough for several builds and changes.

Six years of warranty from the manufacturer, and for those who don't know about Noctua, you can send them an email and they will provide you with free mounting brackets if you upgrade to a different platform and want to keep the cooler. That's the kind of support we're talking about.

The Secufirm2 mounting system from Noctua is very simple and makes the installation of the cooler extremely easy.

In conclusion, this cooler is incredible, but most people will be satisfied with an "Arctic Freezer 34 esports duo". The price of the NH-U12A is a bit steep, but it's precisely because it comes with the incredible customer support, ease of installation, silence, and quality of Noctua. In terms of performance, if you're not doing some extreme OC, the Arctic does about the same job for less than half the price, although it is noisier and more difficult to install. The U12A is worth it for those who are interested in having a very quiet mid-tower PC or for those who don't hesitate to spend a little more money today for better compatibility in the future. For the rest, if your case and RAM allow you to fit the D15, go for it for a similar experience to the U12A, otherwise, the Arctic I mentioned above is the same size as the U12A, performs similarly but is noisier.

Παιδιά είναι απίστευτη η οθόνη.
Όλη μου την ζωή κοιτάω IPS και OLED οθόνες, από άποψη χρωμάτων είναι εννοείται χειρότερη, αλλά και πάλι είναι υπερβολικά καλή για τα χρήματα της. Χρησιμοποιώντας την με κάνει να αναρωτιέμαι αν είναι όντως TN, αυτή η οθόνη έχει τρομερά καλά Viewing Angles, έχω να χρησιμοποιήσω TN Panel πάρα πολλά χρόνια αλλά έχουν φτάσει άνετα επίπεδο VA και σχεδόν IPS από γωνίες θέασης. 144HZ, 1MS και Freesync είναι ιδανικά για το Setup μου, έρχεται με Display καλώδιο ΜΌΝΟ (Όχι HDMI) η βάση της δεν χρειάζεται κατσαβίδια, είναι μόνο ένα Thumb Screw και μετά η οθόνη δεν βιδώνει στην βάση, απλά κάνει Slot και είναι πάρα πολύ στιβαρή, πλαστική βέβαια, αλλά στιβαρή. Η οθόνη μπορεί να μετακινηθεί πάνω κάτω ή και να μπει και σε κάθετη στάση. Συνοψίζοντας, η οθόνη είναι τρομερή για TN Panel, παρά πολύ ωραία χρώματα, παρά πολύ καλά Viewing Angles, πολύ φωτεινή και πάνω από όλα, Gaming με τα απαραίτητα Features. Την συστήνω ανεπιφύλακτα.

Ξέχασα να πω ότι έχει Joystick για ρυθμίσεις (μπράβο LG).

Edit 1: Άν χρησιμοποιήσετε το colour calibration tool των Windows (Πατάτε στην αναζήτηση των windows και αναζητάτε "Calibrate your display colour"), και ακολουθάτε της απλές οδηγίες, τα χρώματα της οθόνης γίνονται ακόμα πιο ικανοποιητικά.
